^ INTRODUCTION.

T

This paper is based upon collections made during the
past seven years. The total number of specimens examined
amounts to nearly 900. In addition to those obtained in or
near the Gull" of Siam, I have been permitted Jlo study,
through the coiu'tesy of the Director of the F.M.S. Museums,
several fine collections made in the Straits of Malacca,
chietly olf the coast of Perak. I have thus been able to
compare large series of several different species from two
entirely different localities, and the results have been of
great interest.

Most of the specimens have been obtained by native
coUecfors, working in conjunction with the fisher people.
Nearly all have been caught at river mouths, where the
water is slightly brackish, either by visiting the fishing
stakes set a short distance out to sea, at the time of the
daily haul, or by obtaining them from the nets or baskets
placed within the river mouth. The collections from Pulau
Angsa, oft' the coast of Selangor, from Bangnara, Patani,
from Hua Hin, and a small one made at the head of the
Gulf of Siam are exceptions to this. They were made in
purely salt water, the snakes being caught while trawling,
or in an ordinary hand net as they lay on the surface of
the water.

Other means than the above of obtaining sea snakes are
less productive. Some species are attracted by a light at
night, and can be speared or netted. Enhydris hardwickii
I have often known caught on a hook and line ; and a
certain number are to be found left on the beach by the
receding tide.

2 Journal of the F.M.S. Museums. [Vol. X,

Sea snakes can be conveyed long distances alive if
attention is paid to their method of transport. They are
best kept in a jar or basket and, if not overcrowded and
placed in a cool spot with enough water to keep them
moist, they will lie almost motionless and live for a week
or more. In water they are continually on the move,
jostling and disturbing one another. The advantage of
obtaining fresh specimens, and of being able to prepare
them one's self is considerable, and adds greatly to their
value for study purposes.

Out of their native habitat sea snakes are helpless and
usually extremely sluggish and unaggressive. Although
I have examined many hundreds of them alive, I have
never seen one make any attempt to bite except under great
provocation. The fishermen in the Gulf, although well
aware of the dangerous nature of their bite, have little
dread of them, and those that happen to get into their boats
with the fish, are picked up by the tail and flung back into
the water.

Judging by the numbers of sea snakes that can be seen
in the Gulf of Siam and Straits of Malacca when travelling
by steamer along the ordinary trade route, it isSpossible
that many new and interesting forms will be found -by deep
sea collecting. In certain localities, when the sea is calm,
they may often be seen in hundreds, chiefly in the early
morning and late afternoon, as they lie on the surface
of the water, apparently to bask in the sun. As soon as
they feel the wash of the steamer, they dive almost vertically
downwards and disappear.

At the head of the Gulf where the coast is well sheltered,
sea snakes abound ; farther down the Peninsula, where
it is exposed to the full force of the N. E. monsoon, they
appear to be less numerous. Two sheltered spots are an
exception to this, namely, the mouth of the Inland Sea,
Singgora, and the Bay of Patani.

By systematically collecting at every available spot,
it has been possible in course of time to search the whole
of the Gulf very thoroughly. The result of this has been
to bring out one noteworthy fact, namely, the curiously
local distribution of many of the species. Certain forms
will be more or less abundant along a small stretch of coast,
at one or more river mouths, and almost or entirely absent
in other parts of the Gulf. The Perak coast collections
shew this same peculiarity, but as they have been made
oyer a much smaller coast hne, it is not so marked. It is
difficult to assign a reason for this phenomenon. The
natural conditions at the mouths of these rivers, generally
mud-flats, are apparently identical, so that it would not
in any way appear to be governed by the food requirements
of these species. It may be that they are estuarinc in their
habits, and that when they get carried out to sea, as must
frequently happen, they perish, either from want of suitable
nourishment, or by being devoured by fish or other enemies.

1920.] Dr. Malcolm Smith : Sea Snakes. 3

Some good collections made well away from the coast
would be of value in helping to elucidate this interesting
problem.

This eccentricity of distribution, as well as minor varia-
tions in scalation and colour which I have found confined to
certain localities only, confirms the view that I have held
for some time, namely, that although the range of a species
may be very great, that of the individuals comprising it is
inclined to be extremely local.

It follows from this that we may expect to find among
sea snakes a considerable number of geographical forms.
No attempt has yet been made to define races for any of the
species, for the reason that few herpetologists have had
sufficient material to work upon. Yet it is clear, when a
good series can be obtained from one locality, and compared
with a series from another, sufficiently remote, that
differences can be found. In many cases the difference
is not great, and is confined merely to slight variation in
the number of scales round the neck and body. A few
shew more distinct changes, not only in the number of
scale rows but in the relationship of the head shields to
one ani^her. Owing to the wide variation which the
indivicl'uals of a species may exhibit in any one locality,
large series are naturally required before the range of
variation of any particular race can be defined. It is
imperative also, if satisfactory results are to be obtained,
that the same methods of examination should be used.
For, according to the way in which the scale rows and
ventral shields are counted, so will the results differ.

In counting the body scales I have endeavoured to find
the minimum and the maximum number of rows. This
necessitates several counts at each spot. The minimum
is upon the neck, usually from two to three, but sometimes
as much as from four to five, heads-lengths behind the
head. The maximum is at mid-body or posterior to it.
In certain forms, such as Enliydris, Thalassophis, Hydras,
the maximum is usually attained by mid-body, but in most
of them, and particularly in (he small headed forms, it
is not reached until well pasi mid-body. The ventrals are
counted from the first biluberculated shield that can be
discovered upon the neck, and all missing ones are allowed
for as if they were present.

The range in the number of ventral shields varies
considerably. It is greatest in that group of species which
are at present defined under " head very small, body very
long and slender anteriorly." It will be seen however, upon
inspection of the tables given, that while the range of the
majority in a series is comparatively limited, a few indivi-
duals at cither end string it out and add greatly to its
number. It is disturbing, after having examined a large
series, and obtained what appears to be the range of varia-
tion of these shields, to find another example which upsets
one's figures to the extent of twenty, thirty, or even more.
Some specimens in my collection differ in this respect so

4 Journal of the FM.S. Museums. [Vol. X,

markedly from what appears to be the normal, that I have
refrained for the present from making any diagnosis of
them! A good illustration of this anomaly will be found
under Hydrophis viperina, a snake possessing so many
unique features that there can be no doubt of its identity.

The measurements of length given are in many cases
approximate only. It is impossible with a specimen coiled
up and hardened by alcohol to be exact. Where total
lengths are concerned a slight discrepancy is of little impor-
tance, but in connection with the sexual variation in the
length of the tail, it is of considerable value.

A full list of all the specimens examined has not been
given in every case. In dealing with large numbers of a
common form this has seemed imnecessary. In other
instances the specimens had been given away to various
Museums before a register of them was undertaken.

The following places are mentioned as having been
collected in : —

In the Gulf of Siam.

Meklong or Meklawng, Tachin, Bangpakong,
Chantabun, Ban Yao, — ^fishing villages at the movi^^ of the
rivers of those names at the head of the Gulf. A reference
such as Chantabun implies the mouth of the Chantabun
river, not Chantabun town.

Koh Kong, a small island ofl' the coast of Cambodia,
just beyond Siamese territory.

Hua Hin, a fishing village on the west side of the Gulf,
80 km. south of the mouth of the Meklawng river, the
nearest fresh water to this village being at

Pran, 20 km. south.

Chumpon, Langsuan, Bandon, Singgora, on the east
coast of the peninsular portion of Siam.

Bangnara in Patani, and Trengganu, on the east coast
of the Malay Peninsula.

In the Straits of Malacca.

Kuala Kurau, Kuala Larut, Londang, on the coast of
Perak.

Bagan Datoh, in the estuary of the Perak river.

Pulau Angsa, 8 km. otf the coast of Selangor, a purely
salt water islet.

Bernam River, Selangor.

Trang, 120 km. south of the island of Puket (Junk
Seylon) .

In Cochin China.

Cap St. Jacques, at the mouth of the Saigon river.

Preliminary diagnoses of Hydrophis lamherti, H.
siamensis, H. consobrinus and H. rostralis appeared in
the Journal of the Natural History Society of Siam, ii, p. 340
(1917) . Further study of these forms in the light of addi-
tional specimens obtained since that date, have obliged me to
modify considerably the remarks I made at that time. The

types of all the species here described will be presented
to the British Museum of Natural History, together with a
selection from the type series.

In the preparation of this paper I have, above all, to
thank Mr. G. A. Boulenger, F.R.S., for the generous help
by correspondence which he has so freely given me at all
times.

I have to thank also Mr. H. C. Robinson, Director of
F.M.S. Museums, and Mr. C. Boden Kloss, for the valuable
collections made under their direction, and sent to me from
time to time.

I am indebted also to Dr. Nelson Annandale of the
Indian Mjseum, to Messrs. N. B. Kinnear and W. S. Millard
of the Bombay Natural History Society, and Dr. Hanitsch
of the Rattles Museum. Singapore, for the loan of specimens
in their charge on various occasions.

Mr. C. L. Groundwater I have to thank for his careful
drawings of the heads of snakes, and Mr. J. R. Bell for
the map.

This snake appears to be a strictly marine species. All
the specimens referred to above were taken in purely salt
water. The Gulf series was caught with a dip net while
lying on the surface of the water, and was taken one
morning while oH" the coast between Hua Hin and Koh Lak.
Altogether some 50 individuals were seen. With the
exception of a few si)ecimens of the common Enhydris
hardwickii, they were the only snakes noticed. Although
I spent the succeedhig week in cruising down the same
coast, going as far South as Lat. 9" (Bandon) for the
express purpose of collecting sea snakes, I did not meet
afterwards w^ith more than half a dozen snakes of any kind.
The weather conditions were the same throughout.

Colouration. — (Gulf series). Black above, yellow to
dark brow^n on the sides and below, the two colours meeting
in a clear line of demarcation. Tail with black dorsal and
ventral bars ; sometimes with a few spots as well. Upper
lip the same colour as the sides of the body.

Some of the darker examples have a yellow stripe
separating the black of the back from the brown of the
under parts. The amount of black upon the back
is variable in width, occupying from 11 to 18 scales, but
in no instance is it narrow enough to deserve the name of
vertebral band. All of this series belongs to Boulenger's
vars. D and E, and they are merely variations of the same

6 Journal of the F.M.S. Museums. [Vol. X,

colour form (bicolor), the yellow merging by every degree
of intensity into brown.

(Straits of Malacca series). Two out of the nine
examples obtained (Nos. 3903, 3915) are coloured as
above, but the remaining seven are quite different. They
have a narrowish black dorsal band occupying about ten
scales, while the rest of the body is yellow, thickly spotted
with black. In the fore-part of the body the upper spots
have coalesced to form a narrow stripe, so that there is
alternately a dorsal band, a narrow yellow stripe, and then
a black one. The dorsal band in the hinder part of the
body is sinuous in out-line or is broken into large spots.
Tail thickly spotted, with the central or ventral part entirely
black. In some examples the whole head is dark brown or
black.

I regard these as Boulenger's form B (Jan's maculata) .
They shew no tendency whatever to intergrade with the
previous form.

In addition to the difference in colour, the Straits series
shews a higher average number of scale rows round the
neck and body, than those from the Gulf. The variatiqc
is as follows : —

Gulf of Siam.

39 to 50 round the neck ; 48 to 60 round the body.

Straits of Malacca.

44 to 55 round the neck ; 52 to 68 round the body.

The question of racial distinction in this widely
distributed snake is a complex one. Boulenger describes
seven colour varieties, but does not attempt to connect them
in any way with geographical areas. Barbour, with the
additional material available in the Harvard College
Museum says "nine easily distinguishable color phases
may be recognized." Six of these, he adds, occur in and
about the Bay of Panama.

I do not tliink he has sufficiently proved that his Hydrus
platurus ornatus is entitled to subspecific rank. Its habitat
he defines as the East Indian Archipelago, and his own
specimen (No. 938) came from Singapore. But, as shewn
by my two series, we may expect to find in the same
locality at least three other colour forms, namely,
Boulenger's B. D. and E.

Hydrophis lamberti Smith.

Journ. N. H. S. Siam, ii, p. 340 (1917).

Description of the type. — Head rather large, neck
thick, body moderately elongate. Eye a little larger than
its distance from the niouth ; rostral considerably broader
than deep, the portion visible above equal to one-third the
length of the internasal suture ; frontal once and a half
as long as broad, much shorter than its distance from the

rostral ; one prae- and two postoculars ; two superposed
anterior temporals ; eight supralabials, the 2nd in contact
with the praefrontal, 3rd and 4th touching the eye ; three
or four infralabials in contact with the anterior chin-shields;
no distinct posterior pair. 45 scales round the neck, 55 round
the thickest part of the body, * those anterior feebly
imbricate, elongate, with truncated apex, and feebly keeled,
those posterior, hexagonal and subimbricate, with a short
central keel ; ventrals distinct throughout, 281, bicarinate ;
subcaudals, 43.

Pale yellowish-grey above, whitish below, with 30 dark
dorsal rhombs on the body, tapering to a point on the
sides ; tail with 4 bars and a dark tip. Head above pale
olivaceous.

Dimensions.—Total length, 860 ; tail, 80, depth of
neck, 18 ; of body, 42 mm.

Dentition. — Posterior maxillary, 10 ; palatine, 10 ;
pterygoid, 23 or 24 ; mandibular, 22, (1 specimen
examined) .

Type. — Female, author's number, 1112. Collected at
4J\e mouth of the Meklawng river. Inner Gulf of Siam, in
Sept., 1916.

Variation. — By fragmentation of the upper extremity
of the 3rd supralabial on one side, it is prevented from
touching the eye. There are no small scales interposed
between the infralabials.

A second specimen of this snake. No. 4010, a juvenile,
total length 335 mm., differs from the type in the following
particulars : — Portion of rostral visible above equal to
nearly half the length of the internasal suture ; 7 upper
labials ; posterior chin-shields small, separated by four
scales ; 302 ventrals ; 38 dark dorsal rhombs.

It was collected at Hua Hin, near the type locality by
Mr. S. G. Lambert, after whom I have much pleasure in
naming it.

This snake is closely allied to H. ornatus (Gray) from
which it differs chiefly in the greater number of scale rows
round the neck and body.

I have referred these specimens to H. godeffroyi as they
agree very well, both with Boulenger's description of this

species in the Catalogue, and with Stejneger's description
of his type from Ishigaki Shima.*

Wall has placed godeffroyi under ornatus, and in this
he may be right. The only reliable character separating
these two species appears to be the number of scales round
the neck and body, godeffroyi having fewer. On the other
hand, the only reliable character upon which I can separate
my lamberti from ornatus is also upon the number of scale
rows, lamberti having more. It is possible that ornatus
is a very variable species, but it is hardly likely that the
range would be so great in one locahty. I have never yet
seen any specimens of ornatus from the Gulf, although they
have been recorded, but until I can fdl in the large gap
which separates my specimens of lamberti from godeffroyi,
I leave all three as they stand. The accompanying table
will shew the ditferences between them.

Variation. — The internasal suture is three times as
long as the interpraefrontal in one of my specimens, only
once and a half times as long in the other. Three postocu-
lars on one side, two on the other, in each example. Two
superposed anterior temporals, the lower one again broken
into two by a vertical suture. Seven supralabials in one*,
eight in the other, the third and fourth touching the eye.
Chin-shields subecpial, the posterior pair, and also partly
the anterior pair, separated by scales. Four infralabials in
contact with the chin-shields.

Boulenger states that the scales on the posterior part
of the body are juxtaposed. I should term mine feebly
imbricate ; they arc certainly not juxtaposed as the word
is meant when applied to such species as H. gracilis or
Enhydris hardwickii.

Colour. — Buffj^-white, with 58 and 68 darkish grey
dorsal bars upon the body and tail. Head greyish-olive
above, white below.

Dentition.— Posterior maxillary, 12 or 13 ; palatine,
8 ; pterygoid, 25 to 27 ; mandibular, 20, (2 specimens
examined) .

* I mention type because the tabulated list of the other three
specimens given is somewhat confusing. The type has 34 scales
round the neck and 43 round the body, an increase of 9. But the
next two examples have an increase of only 5 and 1 respectively,
while the last has none at all, the count for this individual being
33 for both neck and body. It looks like a misprint, but I have
no means of knowing.

1920.] Dr. Malcolm Smith : Sea Snakes. 9

I have recently examined the type of H. tuberculata
Anders., in the Indian Museum, and am in agreement with
Wall (Monograph, p. 220) that it should be placed under
cyanocincfus. It has 31 and 41 scale rows and 312 ventrals.

My largest specimen, a female from the mouth of the
Tachin river, is considerably bigger than any previously
recorded. It measures 1885 mm. in total length, tail 135.

Considering that the type H. aspera Gimther, is said
to have come from Singapore, a noteworthy feature about
most of the specimens is the absence of strong keeling to
the scales. The majority are quite smooth in the anterior
portion of the body, faintly keeled on the dorsal rows in
the posterior part. One example only, a well grown male,
is very strongly keeled ; on the other hand, another male,
half grown, is entirely smooth throughout.

The eye is variable in size but in all the adults is less
than its distance to the mouth. In two examples, Nos. 1315,
1318, it is extremely small.

The anterior temporal shields shew considerable
variation. Normally there are two, placed one above the
othei", the suture between them being horizontal. But the
suture may be obliquely placed, or even almost vertical, so
that the two shields, instead of being superposed, are placed
one behind the other. Cuneiform scales between the
infralabials are present in all, usually a series after the
second.

In the number of scales round the neck and body, the
specimens from the Straits of Malacca shew a slightly
liigher variation than those from the Gulf of Siam. How
far they differ, if at all, from the Indian form (type locality
Bengal), can only be determined when more exact data
from that region are available.

The variation (including 10 embryos), is as follows : —
29 to 35, usually 31 to 33, round the neck.
39 to 47, * usually 41 to 43, round the body.
Ventrals 292 to 377.

Excluding the embryos, the frontal shield is shorter than
its distance to the rostral in 3 examples, equal to its distance
in 10, greater than in 4. The posterior chin shields are in
contact with each other in 4 examples, partly separated in
12, completely separated in 1.

Compared with these specimens, the series from the
coasts of Siam and Cochin China shews a slight reduction
in the number of scale rows, although in other characters,
except possibly in the size of the frontal, it presents no
differences. It is as follows : —

of the body, but does not say from where it has come. Journ.

28 to 33, usually 29 to 31, scales round the neck.

37 to 43, usually 39 to 43, round the body.

Ventrals, 321 to 389.

The frontal shield is as long as its distance to the
rostral in 11 examples, longer than in 12, in 9 of these
being as long as its distance to the end of the snout. The
posterior chin shields are in contact with each other in 12
examples, partly separated in 11.

Colour. — All the young ones taken from the mother
referred to below, belong to Boulenger's Var. A of the
Catalogue. They are light olivaceous yellow, with from
65 to 80 blackish annuli, broadest on the back and joined
together by a strong black stripe running along the beUy.
Head black, with or without a curved yellow band across
the snout behind the nostril, and continued back along the
sides of the head. Posterior half of tail, black.

A comparison of these juveniles with the other more
grown individuals in the series, shows that the ventral part
of the stripe and ventral band gradually disappear with
age. In some of the younger specimens, one-quarter
and one-third grown, these markings can still be traced,
but in the adults they are entirely lost. • All of these are
best placed under C and D, but between the two no dividing
line can be drawn. From the handsome individuals with
bold, black or blue-black dorsal bars, to those in which
the bars are so obscurely marked as to be hardly
recognizable, every gradation can be seen. Head olivaceous
or yellowish, sometimes mottled with blackish.

The adult form with complete jet black annuli and
ventral stripe which is to be found along the Coasts of
India, and which appears to turn up again in the seas
around Formosa I have never seen in this region.

Dentition. — Posterior maxillary, 6 or 7 ; palatine, 7 or
8 ; pterygoid, 15 to 19 ; mandibular, 15 or 16, (7 specimens
examined) .

Breeding. — One pregnant female with 10 fully deve-
loped 5'oung was caught in May off the Coast of Perak.

Mother. — Total length 1690 mm. ; 31 scales round the
neck, 42 round the body, ventrals 337.

Youn^.— Total length, 360 to 380 mm. ; 29 to 31 scales
round the neck, 39 to 41 round the body. The ventrals
could not be counted satisfactorily.

Two other gravid females with their embryos still in
an early stage of development were obtained in January
and May in the Gulf of Siam. Their broods were 5 and 11
respectively.

All the differences between H. wrayi Blgr., and H.
melanosoma Giinth., being disposed of by the above series,
Mr. Boulenger is in agreement with me that his species
should become a synonym of Giinther's. The type of H.
wrayi is from the coast of Perak. The type locality of H.
melanosoma is unknown. Both forms were described
from single examples.

On the whole my series is a very uniform lot, and shews
remarkably little variation. The eye in the adult is always
shorter than its distance to the mouth ; the frontal is as
long as its distance to the rostral in two examples, shorter
than in thirteen ; four infralabials are in contact with the
chin-shields, which are subequal in size ; the posterior pair
are in contact in one example, partly separated in eight,
completely separated in six. Seven supralabials and a
single anterior temporal occur in every example.

Boulenger has described the body scales of his specimen
as " feebly imbricate," while Gunther uses " distinctly
imbricate " for his. I should use the latter expression for
my specimens. Those on the neck and anterior part of the
body are longer than broad, with obtusely pointed extremi-
ties, those on the posterior part are more rounded, and as
broad as or broader than, long. The strength of the
keeling is variable and differs with age. Ventrals distinct
throughout, bicarinate. Fragmentation of the fourth and
fifth supralabials occurs in two examples. In one the
frontals and praefrontals are fused, and in another the sixth
and seventh supralabials are fused on one side. In no
instance do the praefrontals fail to touch the supralabials.
A small cuneiform scale is usually present after the second
and third infralabials.

Colour. — Greenish yellow, the dorsal scales with
black margins, and with 50 to 70 broad black bands, usually
as broad above as below, and about twice as broad as their
interspaces. Some of them are incomplete ventrally. Head
black, uniform or with a yellowish mottling which is chiefly
confined to the snout.

In two examples, Nos. 1121 and 1122, the bands narrow
ventrally, so that upon the belly they are about as broad as
their interspaces. Judging from my specimens, the coloura-
tion of this snake does not appear to undergo much
alteration with age.

Dentition. — Posterior maxillary, 5 or 6 ; palatine, 7 ;
pterygoid, 11 or 12 ; mandibular, 14 (2 specimens
examined) .

Wall, in his Monograph, places both melanosoma and
wrayi under spiralis (brugmansi), and writing again quite
recently (Journ. Bombay Nat. Hist. Soc, XXVI, p. 431, May,

12 Journal of the F.M.S. Museums. [Vol. X,

1919), is still of the same opinion. With a different scale
formula however, more strongly imbricate body scales, and
distinctive colouration (practically a brugmansi reversed),
there seems every reason to keep these species separate.

I do not understand his remark upon the following
page (footnote, Journ. p. 433) , where he also contends that
melanosoma may have to be placed under cyanocinctus.

The natural habitat of this species appears to be the
coasts of India, whence individuals occasionally reach the
shores of the Malay Peninsula. Cantor obtained a specimen
at Penang and I have examined two more from the coast
of Perak.

They agree entirely with Boulenger's description. The
scales round the body are smooth anteriorly, and have a
feeble keel posteriorly. The ventrals are smooth through-
out. One specimen (No. 1202) has no cunieform scales
between the infralabials, an unusual condition in this
species.

Colour. — Greenish-yellow above, the dorsal scales with
black margins, yellowish or whitish below. 44 and 45
narrow black bands upon the body, the bands slightly
enlarged dorsally and ventrally in one, very indistinct across
the belly in the other. Head yellowish, posterior half of
tail black.

Dentition. — Posterior maxillary, 7 ; palatine, 7 ;
pterygoid, 13 ; mandibular, 16 (1 specimen examined).

Under brugmansi (spiralis). Wall has included some
eight or nine other forms, which as far as I am aware are
still considered distinct by other herpetologists. Only two
of them are concerned with this paper, namely melanosoma
and wrayi, and these I have dealt with in discussing the
former.

Hydrophis torquatus Giinther.

Under torauatus I now include three forms which
I have previously considered distinct. No other species of
sea snake that I have j'^et examined shews such distinct
changes, both in scalation and in colouration, within so
small an area. That variation should occur between series
found upon the opposing sides of the Peninsula, was to be
expected, but that two distinct forms should occur in the
Gulf of Siam, with only 350 miles of open sea between them,
was surprising. With a large series of each form however.

1920.] Dr. Malcolm Smith : Sea Snakes. 13

available for examination, I find that they intergrade so
completely with each other, that it seems impossible to
distinguish between them. The three forms are : —

HyDUOPHIS TORQUATLS TORQUATl S.

33 — 37 scales round the neck ; 43 — 49 round the body.

Ventrals 242—306.
Head in the adult pale grey, with a considerable
suffusion of yellow on the top.

Habitat. Coast of Perak and Selangor.

Hydrophls torquatus aagaardl

32 — 37 scales round the neck ; 39 — 47 round the body.
Ventrals 276—325.

Head in the adult dark olive to blackish, with a curved
yellow mark across the snout and along the sides.

Habitat. Coast of Patani, Gulf of Siam.

Hydrophls torquatus siamensis.

29 — 35 scales round the neck ; 35 — 42 round the body.
Ventrals 271—343.

Colouration as in aagaardi.

Habitat. Inner Gulf of Siam.

Coast of Perak, 39 exs. ; Bernam River, Selangor, 2 exs.

Gunther's types came from Penang, so that my Perak
coast specimens are, for all practical purposes, topotypes.
On the whole they are a very uniform lot, and shew more
constancy in scalation than the other two forms found in
the Gulf.

Variation. — The frontal shield, except in one instance,
is always shorter than its distance to the rostral. The
supralabials normally are seven, the first four being usually
complete, the fifth divided, and the last two (rarely are
there three), very small. Chin-shields well developed, the

Eosterior pair in contact with each other or partly separated
y a scale. Four infralabials in contact with the chin-
shields ; cuneiform scales invariably present between the
infralabials, usually a series after the second.

33 — 37 scales round the neck, 43 — 49 round the body,
those anterior elongate, with truncate or bluntly pointed
apex, those posterior more or less hexagonal, imbricate or
subimbricate throughout, with a central tubercle or short
keel. Ventrals distinct throughout, 242 — 306. Average 277.
The number next to 242 is 260.

In adult specimens the depth of the body posteriorly
is from 2 to 2% times that of the neck.

14 Journal of the F.M.S. Museums. [Vol. X,

Co/our.— This varies considerably with age. The
young are whitish, with from 46 to 63 well defmed black
bands, which are often incomplete ventrally. Head black,
with a whitish or yellowish mark across the snout and along
the sides. Adults are pale grey above, yellowish white below,
with darker grey bands, less clearly defined, and usually
incomplete ventrally in the posterior part of the body. In
some aged individuals the bands have almost entirely dis-
appeared, leaving the back more or less uniform grey.
Head grey, with the yellow marks more extensive and less
defined, this latter colour sometimes covering the whole
of the top of the head except a small patch on the crown.

Length. — One example measures 835 mm. in total
length, but the majority of the specimens are under 700 mm.

Dentition. — Posterior maxillary, 8 to 10, palatine,
7 — 8 ; pterygoid, 19 to 22 ; mandibular, 16 — 18 (14 speci-
mens examined) .

Wall, in his Monograph, has included under torquatus
another snake which Boulenger now recognises as diadema,
(the obscurus of the Catalogue, p. 284) . His argument for
combining these two species does not convince me, and the
points of difference upon which he states Boulenger has
separated them, do not appear to me to be the correct ones.
The difference in the number of scales round the neck and
body, and the marked difference in the number of ventrals,
have been overlooked by him entirely.

That these two species cannot be identical is well shewn
by my series, which, as already stated, is topotypical. In
the number of scales round the neck and body, and in the
number of ventrals, they agree very closely with Giinther's
description.

Hydrophis torquatus aagaardi, subsp. nov.

Similar to H. t. torquatus, but with average fewer
number of scale rows round the body, greater average
number of ventrals, larger frontal, and darker colouration.

Type. — Adult male, author's number, 1169, collected
July 1917, off the coast of Bangnara, Patani, Gulf of Siam,
by Mr. C. J. Aagaard.

Number of specimens examined, 44, all from the type
locality.

Variation. — The frontal shield in this form is very
variable both in size and shape. In 26 examples it is as
long as its distance to the rostral, in 7 examples it is shorter
than, and in 9 it is longer than, its distance from that shield.
In No. 1267 it is considerably shorter than its distance to the
rostral, in No. 1273 it is as long as its distance to the end
of the snout, yet there can be no doubt that these two
represent the same species. Two postoculars occur in one
example. As with the typical form, the temporal shield
is verj' constant, a single scale being present in every
instance. The supralabials however are more subject to
division in aagaardi, and fragmentation may occur in any
of them after the second.

1920.] Dr. Malcolm Smith : Sea Snakes. 15

32—37, usually 33—35, scales round the neck, 39 — 47,
usually 42 — 45, round the body. Ventrals 276 — 325.
Average 297.

Colour. — Greyish or greenish-grey above, yellowish
white below, with from 55 — 68 dark grey or blackish annuli,
which may be incomplete \entrally. Head black to dark
olive, with a yellow band across the snout and continued
back along the sides of the head. Sometimes a few yellow
spots un the frontal and parietal shields. With age all the
markings lose definition, but both this form and the
succeeding one are more prone to keep their markings in
adult life than the typical form.

H. t. aaqaardi represents a race intermediate between
H. t. iypica and H. t. siamensis, resembling more the for-
mer in scalation and the latter in colour. But for the
discovery of this form, I should still have regarded H. t.
.siamensis as a species distinct from H. t. typica.

AH the specimens were taken in deep clear sea water,
being caught in trawling nets, some as far as 20 miles from
the coast. I have much pleasure in naming this subspecies
after Mr. C. J. Aagaard, of the Bangnara Rubber Estate,
Patani, to whom I am indebted for so fine a series.

Two other specimens, Nos. 1276, 1175, taken off the
same coast and in company with typical specimens of H. t.
aagaardi, must be mentioned here. They have 34 and 37
scales round the neck, and 43 and 51 round the body
respectively. Ventrals 302 and 292. Both are females and
both have two superposed temporal shields on both sides.
In other respects they agree entirely with H. t. aagaardi.

No. 1276, with 43 scale rows I should have referred
without much hesitation to this form, for the same variation
in the temporal shields is to be found in its northern ally
H. t. siamensis. No. 1175, with 51 scale rows — no, less
than 4 in excess of what is to be found in any other specimen
of my series — is not so easily disposed of. For the present
I regard them both as aberrant examples of H. t. aagaardi.

Hydrophis siamensis, Smith, J. N. H. S. Slam, II, p. 341 (1917) ;
idem, Journ. Bombay N. H. S., XXVI, p. 682 (1919).

Similar to H. t. torquatus, but with fewer scale rows
round the neck and body, greater average number of
ventrals, larger average frontal and darker colour ; also in
a tendency of the temporal shield to subdivision.

Type. — Adult male, author's number 1151, collected
at Ban Yao, Inner Gulf of Siamv Sept., 1917.

Number of specimens examined, 84.

Variation. — The frontal shield is as long as its distance
to the rostral in about 50% of the specimens ; in the
remainder it is shorter, with two exceptions, in which it is
nearly as long as its distance to the end of the snout. The

1 6 Journal of the F.M.S. Museums. [Vol. X,

temporal shield is not so constant as in the other two forms,
in some examples having undergone fragmentation into 2,
3 or 4 pieces. It is noteworthy however, that this irre-
gularity is almost entirely confined to the individuals of one
locality. Of my 84 specimens, division of this shield on one
or both sides occurs in 16, of which 14 are from the mouth
of the Chantabun river.

In 7 embryos extracted from their mother, a single
shield is present in 5, while in the remaining 2 it is divided
The mother has one shield on one side, two on the other.

The supralabial shields are subject to the same irre-
gularity as in aagaardi.

29 — 34, usually 31 — 33, scales round the neck, 35 — 42,
usually 37—39, round the body. Ventrals 271 — 343.
Average 300. (Chantabun, E. coast series, 296 ; Meklong,
W. coast series, 306).

In the actual increase in the number of scale rows
round the body, as compared with that round the neck, this
form differs from both the preceding ones. In siamensis
the body count is from 5 — 9, usually 6 — 8, more than the
neck, whereas in the other two it is from 6 — 11, usually
8—10.

Colour. — As in aagaardi, except that the yellow upon
the head is inclined to be more diffuse. In a few examples
it is in excess of the ground colour. Most of the specimens
are completely banded. Two individuals, Nos. 1279, 1298,
have the head and back almost entirely uniform darkish
grey ; other examples are characterized by a broad irregular
ventral band, either broken or continuous.

Distribution. — From Meklong on the Western side
of the Gulf to Koh Chang on the East. It is particularly
abundant at the mouths of the Meklong and Chantabun
rivers.

Dimensions.— Xs will be seen from a study of the
annexed tables, the two forms in the Gulf appear to grow
to a larger size than that found in the typical locality.

Specimens of this snake which I sent to the Museum
of the Bombay Natural History Society, have been diagnosed
by Col. Wall as Hydrophis cyanocinctus. My reasons for
dissenting from his opinion have already been given in the
Journal of that Society (l.c.s.), and his reply to my criti-
cisms later (p. 864) do not in any way influence my previous
conclusions.

The tables of FI. t. siamensis and H. cyanocinctus
which I have given here should be sufficient to shew that
the variation in the number of scale rows in these two forms
is not the same. Nor can his other remarks Avith regard to
scalation, size and colouration, in view of the large series
now available for examination, be maintained. As I iiave
already remarked, the two snakes when compared side by
side — however much they may be alike on paper— are to me
so different, that 1 am surprised that Col. Wall should ever
have thought them identical.

1920.] Dr. Malcolm Smith : Sea Snakes. 17

Breeding. — ^Young are born in February and March.
Two females are of interest, as shewing the diflference in
the size of the embryos due to nutrition. Tlie parents are
of equal length 925 mm. — but while one contained a brood
of 8, the other had only 3. Both broods 'are apparently
fully developed. The average length of the family of 8
is 285 mm., that of the other 325.

To this race I refer the specimen recorded by Flower
from the Gulf of Siam (P.Z.S., 1899, p. 687, No. 190)
as Hijdvophis ohscarus (now diadema) . I count it to
have 32 and 38 scale rows, with 302 ventrals and 10
posterior maxillary teeth. It is I believe the only record of
diadema from the Gulf.

Hydrophis caerulescens (Shaw).

Hydrophis caerulescens, Bouleng., Cat. Sn. B. M., p. 275 (1896) ;
idem, Fauna Malay Pen., Kept, and Batr., p. 187 (1912) ; Wall,

Distira caerulescens, Wall, Mem. Asiat. Soc. Bengal, ii, (8),
p. 231 (1909).

This snake has a wide distribution, and from Bombay
to C.ochin China appears to be found almost everywhere
along the Asiatic coast. Curiously enough it has not yet
been recorded from the Malay Archipelago,

With its large number of strongly keeled scales round
the neck and body, it is well differentiated from most othervS,
and has not been subject to much confusion in the past.

Boulenger's conception of this species, as regards the
number of scales round the neck and body, is without doubt
too restricted. Wall, working on more material, found the
variation to be considerably greater. He was dealing
however, chiefly with Indian specimens. With the large
series before me now (98 examples), from the coasts of
Siam and the Malay Peninsula, the range can be still further
increased. Between the most extreme forms, such as one
from Orissa (No. 14493, Indian Museum), with 43 scales
round the neck, and 51 round the body, and another of
mine (No. 1352) from the Gulf of Siam, with 31 round the
neck and 38 round the body, the difference is so great that
they might be considered distinct, were it not that the
gradation between them can be easily traced.

I have only been able to examine a small series from the
Indian coasts, and between them and examples from the
Straits of Malacca I can find no marked difference. Those
from the Indian coasts have a slightly higher average num-
ber of scale rows, and a larger series might shew this
character to be constant, the maximum average number
of scale rows obtaining in that region. W^all also has
pointed out that this sea snake possesses a character which
is almost pecuHarly its own, namely, that the parietal shield
nearly always fails to touch the postocular. His observa-
tion, derived chiefly from Indian specimens, applies equally
well to my series from the Straits of Malacca^

As shewn later, this character is absent in H. caerulescens
thai. I have found it present also, as an abnormality, in
H. klossi and H. consobrinus.

i8 Journal of the F.M.S. Museums. [Vol. X,

I therefore group all these together under forma
caerulescens (type locality, Vizagapatam) .

Hydrophis caerulescens caerulescens.

33 to 43 scales round the neck, 42 to 53 ^ round the
body ; ventrals, 253 to 337 ; parietals usually not in contact
with the postocular.

Colour. — Greyish above, yellowish-white below, with
from 40 to 60 dark bands which may be incomplete ven-
trally. The young have the bands very clearly defined, but
with age the markings lose definition, and in some adults
are scarcely recognizable, the back being almost uniform
grey. Head blackish in the young, darkish grey in the
adult, sometimes with a light streak behind the eye -.

Habitat. — Shores of India and Burma and west coast
of the Malay Peninsula,

Number of specimens examined, 65. Coast of India,
9 ; Mergui Archipelago, 2 ; Straits of Malacca, 54.

The actual variation between my series from the Indian
coast and the Straits of Malacca is as follows :—

India. 35 to 43 scales round the neck, 45 to 51 round
the body ; ventrals, 269 to 332.

Straits of Malacca. 33 to 42 (usually 37 to 39) scales
round the neck ; 45 to 51 (usually 45 to 48) round the body ;
ventrals, 253 to 319 (average, 290).

Variation. — The frontal shield in 11 examples is as
long- as its distance from the rostral. In 3 examples the
posterior chin-shields are absent. The parietal shield
touches the postocular on both sides in 3 examples only,
and on 1 side in 7 more.

Specimens from the Gulf of Siam I distinguish as

Hydrophis caerulescens thai ', subsp. nov.

Dift'ers from the tj'^pical form in having fewer scale
rows round the neck and body, and in the parietals usually
being in contact with the postocular.

31 to 38 (usually 33 to 36) scales round the neck, 38
to 49 (usually 41 to 45) round the body ; ventrals, 262 to
334.

Colour. — The dark bands upon the body, although not
so conspicuous in adults as in juveniles, do not shew that
tendency to become entirely lost with advancing age as in
the preceding form.

Habitat. — Coasts of Siam and Cochin China.

Number of specimens examined, 42 (Gulf of Siam, 40,
Cap St. Jacques, 2) .

Type. — Adult male, author's number, 1353, collected
at Hua Hin, Gulf of Siam, in June 1917.

^53 is recorded by Wall (Monograph).

^The presence of this streak is not mentioned by any author,
although Giinther very clearly figures it. It occurs in about 30%
of my specimens.

'Thai = Siamese, pronounced tai,

Variation. — The frontal in 15 examples is as long as
its distance from the rostral ; in one it is longer than its
distance ; in no examples are the chin shields absent ;
in two instances the posterior pair are in contact with
each other ; the parietal shield fails to touch the postocular
in two examples only on both sides, and in one example
more on one side. Average ventral count, 291.

Dentition. — H. caerulescena has an unusually large
number of teeth in the maxillary bone behind the poison
fangs. I find the dentition as follows : — Posterior maxil-
lary, 13 to 16 ; palatine, 7 or 8 ; pterygoid, 21 to 23 ;
mandibular, 21 to 25 (7 specimens examined) .

Boulenger's description was drawn up from a single
specimen, but with the large amount of material now
available this can be considerably augmented, and it will
be simpler to redescribe the species than to add a number
of points to his original remarks.

Description. — Head small, body long and slender
anteriorly, the posterior depth in the adult being from 2^/^
to 3 times that of the neck. Snout distinctly projecting
beyond the lower jaw ; eye equal to or slightly less than
its distance from the mouth. Rostral as broad as deep, or
broader than deep, the portion visible above equal to from
1|3 to 213 the internasal suture ; frontal small, longer than
broad, usually shorter than its distance from the rostral ;
one prae- and one postocular ; one large anterior temporal ;
usually five supralabials, 3rd and 4th touching the eye,
sometimes a small sixth ; two pairs of cliin-shields, subequal
in size, the posterior pair partly or completely separated ;
four infralabials in contact with the chin-shields.

23 to 27 scales round the neck, 31 to 39 round the body,
imbricate throughout, the anterior ones elongate with
bluntly pointed extremities, smooth or faintly keeled, the
posterior ones broader with more rounded extremities and
more strongly keeled. Ventrals distinct throughout, 360 to
402.

Greyish or greenish above, yellowish or whitish below,
with from 50 to 75 dark bands. In the fore part of the
body these are as broad above as below and slightly broader
than their interspaces, behind usually twice as broad above
as below. In some the bands are incomplete ventrally,
and in some they are linked up by a black line running along
the ventral shields ; or the lower part of the neck may be
entirely black. Head blackish to olivaceous, lighter on the
snout, sometimes with an indistinct horse-shoe shaped
mark, its front across the praefrontals and the ends upon
the temporal shields. The young at birth are white, with

20 Journal of the F.M.S. Museums. [Vol. X,

clearly defined black bands. Head entirely black, or with
a yellow spot behind each nostril, or with the horse-shoe
mark ; with age the bands become less distinct but are
always clearly recognizable.

Dentition. — Posterior maxillary, 5 or 6 ; palatine, 7 ;
pterygoid, 9 or 10 ; mandibular, 13 or 14 (4 specimens
examined) .

Variation. — The frontal shield is very variable as
regards size, but except in one example is always shorter
than its distance from the rostral ; in one example only it is
nearly as small as in the type. One example has the 4th
supralabial touching the eye on one side, and the 3rd,
4th and 5th on the other. Fragmentation of the upper
labials, and cuneiform scales among the lower are rare,
the former condition occurs in two examples, the latter in
one.

//. klossi with its uniform rows of imbricate scales,
appears to be closely allied to H. nigrocinctus Daudin, from
the Indian seas, and H. melanoceplialus Gray from the
Riu Kiu Islands. In the number of scales round the body
these three forms are much alike, but klossi has more
ventrals, a smaller frontal and fewer supralabials.
Nigrocinctus also has two anterior temporals.

As will be seen by inspection of the accompanying
tables, the Siamese form has a slightly higher average
number of scale rows than the Malaccan form. The varia-
tion is as follows : —

Straits of Malacca, forma typica.

23 — 25 scales round the neck ; 31 — 35 round the body.
Ventrals, 361—386 (av. 372).

Gulf of Siam.

23 — 27 scales round the neck ; 33 — 39 round the body.
Ventrals, 360—386 (av. 372) .

Breeding. — In the Gulf this occurs in March, from 2
to 5 young being produced. Females taken off" the coast
of Perak in September, shewed the embryos well advanced
in development.

Hydrophis consobrinus Smith.
Journ. Nat. Hist. Soc. Siam, II, p. 341 (1917).

Diagnosis. — Posterior maxillary teeth, 5. Head very
small, body very long and slender anteriorly ; 25 to 31 scales
round the neck, 36 to 45 round the body ; ventrals, 328 to
401. A single anterior temporal. Head Avith a curved
yellow mark above.

Description. — Head very small, body very long and
slender anteriorly, its greatest depth in the adult being from
two and a half to three times that of the neck. Eye
slightly greater than its distance from the mouth ; rostral
broader than deep, visible above ; frontal once and one
third to once and a half times longer than broad, as long
as or slightly shorter tlian its distance to the rostral ; one

prae- and one, rarely two, postoculars ; a single large
anterior temporal succeeded by another not so large, and
with 4 to 7, usually 5 or 6, small scales in a series between
them and behind the parietals. Six supralabials, 2nd
largest and in contact with the praefrontal, 3rd and 4th
touching the eye, 6th very small. Chin-shields well deve-
loped, subequal, the posterior pair in contact or partly
separated. Four infralabials in contact with the chin-
shields.

25 to 31 scales round the neck, 36 to 45 round the
thickest part of the body, those on the neck imbricate,
elongate, with truncated apex, those posterior hexagonal,
subimbricate, with a small tubercle or short keel. Ventrals
distinct throughout, bicarinate, 328 to 401.

Colour. — Greyish above, yellowish or whitish below,
with dark grey bars or bands, 60 to 80 in number. In the
fore-part of the body these bands are as broad above as
below, and broader than their interspaces ; behind broadest
on the back, narrowing on the sides, and usually incomplete
across the belly. Head blackish or greyish, with a curved
yellow mark, its front on the nostrils, and reaching back
along the sides of the head. Often a connecting bar across
the frontal and another across the parietal shields. With
age these markings lose definition.

Variation. — The frontal shield touches the nasals in
one example ; the anterior temporal by fusion with the
6th supralabial sometimes reaches the border of the mouth ;
fission of the 2nd supralabial in one example produces a
pseudo-loreal (No. 2216) ; marginal fragmentation of the
supralabials is not present in any example ; usually there
is a single cuneiform scale after the third infralabial.

Dentition. — Posterior maxillary, 5 ; palatine, 7 ;
pterygoid, 15 or 16 ; mandibular, 13 or 14 (3 specimens
examined) .

Type. — Adult male, author's number, 1132 ; collected
at the mouth of the Bangpakong river, Inner Gulf of Siam,
in February, 1917.

Habitat. — Coasts of the Malay Peninsula, Siam and
Cochin China.

Remarks. — H. consobrinus appears to be most nearly
related to H. brookii Giinther, and H. floweri Boulenger,
two species described from the north coast of Borneo ; and
it is not unlikely that it will ultimately have to be united
with one or other of them. Neither, however, accord
entirely >vith the scalation presented by my large series of
consobrinus, and until more is known about the variation
existing in these two forms, I leave mine distinct.

With the true status of this snake therefore still uncer-
tain, I refrain from describing geographical races, although
the form found in the Straits of Malacca is quite distinct
from that found in the Gulf. The case is further com-
plicated by the three examples from Cap St. Jacques, which

22 Journal of the F.M.S. Museums. [Vol. X,

also differ from the Gulf series, but shew a tendency to
revert back towards the Malaccan form. The variation is
as follows : —

Gulf of Siam.

25 to 27 scales round the neck. 37 to 41 round the
body. Ventrals, 358 to 401. Av. 377.

Number of specimens examined, 18. The frontal is
as long as its distance from the rostral in 17, shorter than
in one.

Straits of Malacca.

27, usually 29 to 31, scales round the neck. 39 to 45,
usually 41 to 43, round the body. Ventrals 328 to 396. Av.
367.

Number of specimens examined, 50. The frontal
shield is as long as its distance from the rostral in 33
examples, shorter than in the remainder.

Cap St. Jacques.

29 to 30 scales round the neck. 41 to 43 round the
body. Ventrals, 387 to 400.

The frontal shield is longer than its distance to the
rostral in one example, equal to in two.

With the typical form of fasciatus as I now conceive
it, this species should not be confused, but from atriceps,
with its lower scale formula, separation may at times be
difficult. The yellow head markings of consobrinus are,
however, very consistent, and in fresh specimens an almost
infallible guide. A small but very useful differential
character in scalation between them is also to be found in
the scales behind the parietal shields. In atriceps there
are usually three small scales lying in a series between the
large posterior temporal shields and behind the parietals.
Rarely there are four or two. Consobrinus on the other
hand has usually five or six in the series, sometimes four,
rarely seven, their number depending upon the size of the
posterior temporal shields. As in atriceps, the posterior
temporal shield of consobrinus may be divided by a vertical
suture into two.

H. klossi, which in the Gulf has often the same number
of scale rows on the body as consobrinus, can be distin-
guished by its distinctly imbricate scales, fewer supralabials
and proportionately larger head of olivaceous colour.

Breeding. — A gravid female taken off the coast of
Perak in December contained 7 embryos in an early stage of
development. Another taken in February contained 5 fully
developed young, varying from 330 to 340 mm. in length.
The mother measured 880 mm., tail 70.

Hydro phis fasciatiis as it is known at present, is said
to be distributed from the coasts of India to China and New
Guinea. The evidence for its existence in the Far East
is somewhat obscure, and it will be as well to discuss the
specimens which have contributed to the statement before
proceeding further.

Hijdrophis lindsayi (Gray) . The type and only known
specimen is in the British Museum. It has 31 and 48 scales
round the neck and body respectively, and 452 ventrals\
Its habitat, China, is vague, and Mr. Boulenger tells me he
does not attach much importance to it.

H. fasciatus has been recorded by Boettger from
Manila, and also from Miyakoshima, Riu Kiu (Loo Choo)
Ids. The former specimen has been placed by Van
Denburgh and Thompson under their Disteira cincinnatii-
but, as I shall presently endeavour to shew, their snake
agrees so closely with the form of fasciatiis which is found
in the Gulf of Siam, that I think they should be lUTitcd.

Stejneger has referred the Japanese example to Disteira
mehiiwcephala,' but presumably has not examined it. He
is probably right in doing so, l3ut its scale formula is so
near to that given by Van Denburgh and Thompson for
some of their Manila specimens, that in the light of present
knowledge it might be as well to reserve opinion.

Stejneger's suggestion that nielanocephala may ulti-
mately prove to be only a race of fasciatus (p. 421), is not
in my opinion borne out by the example he has kindly
sent me. With its imbricate scales, those on the posterior
part of the body having more rounded edges rather than
the regular hexagons of fasciatus, with its 7 or 8 supra-
labials, and 7 posterior maxillary teeth, I believe it to be
quite distinct. Fasciatus has only 5 teeth beliind the poison
fangs, and this number appears to be constant.

Hydrophis atriceps Giinther. The type is from the
Gulf of Siam, and it has 28 and 44 scales round the neck
and body respectively, and 3()4 ventrals. Such a scale com-
bination is very typical of the form which is found in the
Gulf, and diti'ers distinctly from the one which inhabits the
Straits of Malacca, and apparently also the entire Sea of
Bengal. The dit^erence is so marked that it is entitled to
subspecific distinction, and in choosing a name for it one
cannot do better than revive Giinther's.

' For the scale formulae of H. lindsayi, H. atriceps, and
Cantor's specimen of H. fasciatus from Penang, I am indebted to
Mr. Boulenger.

I recognize two forms which I define as follows : —

Hydrophis fasciatus fasciatus.
27 to 33 scales round the neck. 47 to 58 round the
body. Ventrals 400 to 504 (531, Wall). Av. 455.

Habitat. Coasts of India and Burma to the Malay
Archipelago.

Hydrophis fasciatus atriceps.

25 to 30, usually 27 to 29, scales round the neck. 40
to 49, usually 43 to 45, round the body. Ventrals 327 to
452. Av. 366.

Habitat. Gulf of Siam and South China Sea to Malay
Archipelago.

Both forms appear to extend their distribution into the
seas of the Indo-Australian Archipelago, but the particular
range of each one has yet to be determined.

Hydrophis fasciatus fasciatus.

The type specimens are in the Berlin Museum. Their
habitat is unknown. Dr. Nelly de Rooy has kindly made
enquiries for me and she is informed that they have 29 and
30 scales round the neck, 52 and 53 round the body, and
457 ventrals. This description accords with the form found
west of the Malay Peninsula, and shoukl therefore be
designated the typical one.

The figures I have given above for this form, are based
chiefly upon my series from the Straits of Malacca, but all
the specimens that I have examined from the Indian coast
also agree with them. Wall records examples from India
with a lower body count, but as he enumerates at mid-body,
another 3 or 4 may be added to his figures to arrive at the'
maximum number. Boettger records two specimens from
Madras with 52 and 56 respectively.

This range of variation will also include H. rhombifer
BIgr., (56 scales round the body, type locahty coast of
Perak), and //. leptodira Blgr. (58 scales round the body,
type locality Mouth of the Ganges* ?), and that his two
forms should now become synonyms of fasciatus, Mr.
Boulenger is agreed. Wall, in his Monograph, came to this
same conclusion, but in his conception of the species has
included H. hrookii Giinther, a snake which I believe to be
quite distinct.

Further collections from the coast of India may possi-
bly inodify the definition of this form as given above, but
it will not alter the separation of the Malaccan race as
distinct from that found in the Gulf of Siam.

Variation. — The following remarks concern my series
from the Straits of Malacca. The rostral is as high as
broad in one example ; the frontal is shorter than its dis-
tance to the rostral in two examples ; two postoculars occur
in two examples ; the praefrontal shields fail to touch the
supralabials on both sides in three examples, and on one

side in two more ; the posterior temporal is as large as the
anterior or larger ; a cuneiform scale is present in all after
the third infralabial.

Colour. — None of my series (except one juvenile) is
completely banded. Above they are pale grey, with from
60 to 80 dark grey dorsal rhombs, which in some of them
are continued round the body as pale bands, but in the fore
part of the body only. The transition from the dark dorsal
rhomb to the paler ventral band occurs with a fairly clear
line of demarcation. Below creamy white ; head, neck
below, and anterior part of belly, black. One specimen.
No. 1150, is very pale, being almost white in the posterior
part of the body, with the dorsal marks only just visible.

To H. fasciatiis typica I refer the H. gracilis recorded
by Hanitsch (Kept. Raffles Mus., 1897, p. 101) . For its scale
formula see the table.

The scalation and distribution of this form have already
been dealt with.

Number of specimens examined, 60 ; Gulf of Siam,
58 ; Cap St. Jacques, 2.

The sudden and marked diminution in the number of
scale rows and ventrals, as well as the alteration in colour,
which characterizes nearly all my specimens from the Gulf
ot Siam as compared with those from the Straits, induced
me for a long time to believe that they were distinct. I
cannot however find any certain grounds upon which they
can be separated. Between an example from Pulau Angsa,
with 57 scales round the body, 504 ventrals, and the back
with dark rhomboidal marks, and another from Ban Yao
with 41 scales round the body, 327 ventrals, and the body
marked with complete bands, there is every degree of
gradation.

Variation. — As one would expect, with fewer scales
round the body in proportion to those upon the neck, this
form is relatively stouter anteriorly than the Malaccan one.

The rostral shield may be as broad as high ; the frontal
shield in six examples is longer than its distance to the
rostral, in two of these being in contact with the nasals. In
No. 1261 the frontal is very small, much shorter than its
distance to the rostral. The anterior temporal in one
instance (No. 1252) is divided on one side to form two
superposed shields ; the posterior temporal shield is seldom
as large as the anterior, and is often divided in two by a
vertical suture. Normally the supralabials are undivided,
but in one instance there is fragmentation of the fifth. In
five examples the temporal shield reaches the border of the
mouth to the exclusion of the sixth and seventh labials. A

26 Journal of the F.M.S. Museums. [Vol. X,

single cuneiform shield is invariably present after the third
infralabial. 25 scales round the neck occurs twice in the
series, 30 twice ; 40 scales round the body occurs once, 49
five times. Ventral variation. Males, 327—396 ; females,
338—452. The ventral count of 452 (No. 2876) appears to
be quite abnormal, the numbers next to it in succession
being 434, 420, 416, 413. H. lindsayi agrees closely with
this example.

Colour. — Greyish above, greenish- or yellowish-white
below, with from 50 to 75 blackish annuli or dorsal bars.
Head and anterior part of body below entirely black at all
ages ; sometimes a yellow spot behind the nostril or the
eye. In No. 2873 these spots have coalesced to form a
complete yellow horse shoe. All the specimens from Ban
Yao and Chantabun are completely banded, the band being
paler above than below but without any clear line of demar-
cation ; those from Cap St. Jacques and the western side
of the Gulf are, with one exception, coloured as the
Malaccan specimens. Two specimens from Bangpakong
form a connecting link between these two forms. No. 1309
has dorsal and ventral bars, the two meeting in a point on
the side of the body.

Distribution. — Nearly all my specimens are from the
mouths of two rivers, Chantabun and Ban Yao. At the
latter spot it is the predominant form, nearly all the sea
snakes coming from that locality belonging to this species.

Breeding. — In the Gulf young are born in February and
March, from 4 to 8 being produced. Their markings are
practically black and white.

Dentition. — The teeth of H. fasciatus are as follows : —
posterior maxillary, 5 ; palatine, 6 or 7 ; pterygoid, 12 to 16 ;
mandibular, 14 or 15 (8 specimens examined).

I have not examined any specimens of Disteira cincin-
natii Van Denburgh and Thompson, from Manila, but as
already stated their description agrees so closely with that
of my specimens from the Gulf, that I cannot but think
they should be united. The slightly lower number of scale
rows (38, 39) round the body, as shewn in three specimens
of their series, would be accounted for by local variation,
or perhaps the difference in our methods of counting.

Hydrophis gracilis (Shaw).

I believe now that my H. rostralis is only a gracilis after
all. I was mislead in the first instance by the large number
of body scales (35 to 41) which I found in my series, the

1920.] Dr. Maixolm Smith : Sea Snakes. 27

accredited count for gracilis being 29 to 33. Since then I
have obtained a specimen having 33, and Wall has also
published an account of a large series of gracilis obtained
on the Indian coast (Journ. Bombay, Nat. Hist. Soc. 1. c. s.).
His maximum is only 33, but his count is made at. mid-body,
and I find on counting my own specimens at that point, an
allowance of from 2 to 4 scales may be made for the
difference in position.

This brings them much nearer to my own specimens,
and as there appears to be no other character by which they
can be separated, I unite them. Wall's series is a fine one
of 36 examples, and should be fairly representative of the
locality (Madras). After allowing for all discrepancies in
our method of counting, however, there still remains a con-
siderable difference between his series and mine with regard
to the number of scales round the neck and body. I tenta-
tively define the two forms as follows : —

Madras Coast.

17 — 19 round the neck ; 29 — 37 round the body. Ven-
trals, 215—297. Av. 251.

Malay Peninsula and Gulf of Siam.

19 — 23 round the neck ; 33 — 41 round the body. Ven-
trals, 250— 302. Av. 279.

Two races appear to be clearly indicated, but with the
type locaUty of this snake unknown, it would be as well to
know something about the forms found elsewhere before
proceeding to name them.

Variation. — The variation in my specimens is as
follows : — Eye equal to or slightly less than its distance from
tlie mouth ; rostral as broad as high or a Uttle broader than
high, the portion visible above equal to three-quarters or the
entire length of the internasal suture ; frontal usually
shorter than its distance to the rostral ; five or six suprala-
bials, in one example only the fourth shield touching the
eye. Fragmentation of the supralabials does not occur in
any example, nor are there any small scales interposed
between the infralabials.

Colour, (in alcohol). Pale bluish-grey on the upper
half of the body, yellowish or whitish on the lower, the
young with indistinct darkish dorsal bars or complete bands.
Head grey, yellowing with age.

No. 1105 has 55 bands upon the body, about as broad
as their interspaces on the sides of the body, slightly dilated
dorsally and ventrally ; on the posterior part of the body
they are very indistinct. Tail grey, blackish at the tip.

Dentition. — Posterior maxillary, 5 ; palatine, 8 ; ptery-
goid, 10 — 12 ; mandibular, 13 (3 specimens examined).

The type of my original H. rostralis is No. 1102, in the
Selangor Museum, Kuala Lumpor.

One of the specimens was seen to fall from the claws
of a fishing eagle, and was picked up still alive and quite
undamaged at some distance inland. This incident possibly
explains the records of sea snakes which have been occa-
sionally discovered at a considerable distance from their
natural habitat.*

For a small series, mine shew a wide range in the
number of scale rows. They vary from 27 to 34 at the
neck and from 37 to 50 round the body. Ventrals 181 to
264. A reference to the table will show that the extremely
low ventral count of 181 is confined to a single individual.
No. 2716. But for this specimen the variation in the
number of these shields would be 232—264, a range which
is almost exactly in accordance with what has been already
given by Boulenger and Wall. It is an excellent example
of the abnormality in ventral shields to which I have refer-
red in the preliminary remarks.

As shewn by the table, the two specimens from Cochin
China have a higher body count than any found in the Gulf.

Colouration. — Grey above, white below, with from 28
to 34 dark grey dorsal rhombs which are usually confluent
vertebrally. My one juvenile is beautifully and con-
spicuously marked, but with age the pattern becomes
obscured, and in some individuals has entirely disappeared,
leaving the back of a uniform grey colour, which is
separated from the white of the belly by a clear line of
demarcation.

Dentition. — Posterior maxillary, 5 ; palatine, 7 or 8 ;
pterygoid, 14 to 17 ; mandibular, 17 (4 specimens
examined) .

another. Chin-shields well developed (as figured by
Giinther, pi. XXV, fig. B), in all three examples. Wall

* That numbers of sea snakes fall victim to birds of prey, was
once demonstrated to me on visiting a large flat-topped buoy lying
some miles out to sea in the Bight of Bandon. The top of this
structure was covered with the dried bodies of snakes — chiefly
Enhijdris hnrcfyvickii — the birds having brought their victims
there, and i'.fter devourin,' the internal organs, left the remainder
to be disposed of by the elements.

states that in 17 individuals examined by him, three infrala-
bials only were in contact with the chin-shields. All my
specimens have four, the first three in contact with the
anterior pair.

Colour. — ^The adult is light greyish above, yellowish-
white below, with 50 broad black dorsal bars which are in-
distinctly carried round the body as narrow bands. The
young have the back pale olivaceous, and the bands (40 and
48) more distinct below. Head pale olive with a dark mark
on the snout.

Dentition. — Posterior maxillary, 8 — 9 ; palatine, 9 ;

examined) .

I have now examined 17 examples of this snake, all
obtained from various localities at the head of the Gulf.

The following points may be added to my recent
description. The eye may be slightly greater than its
distance from the mouth. 27 to 30 scales round the neck,
31 to 35, usually 33, round the body. Ventrals 218 to 256.

The young may have a pale band across the snout and
extending along either side of the head to join the white
of the under surface.

Dentition. — Posterior maxillary, 5 ; palatine, 7 ; ptery-
goid, 20 to 22 ; mandibular, 18 or 19 (2 specimens
examined) .

Ouwen's coloured illustration of this species is not very
representative of my specimens. The body is too elongate
and the bars are much too dark.

In cranial and in external characters this species differs
so much from the genotype, T. anomalus, that the mere
presence of a pair of internasals seems insufficient reason
for placing them together. As a matter of fact, in one of
my specimens these shields are almost entire, as is usual
with Hydrophis, while in the others they are variously
divided, and it would seem more correct to consider them
as subject to irregular fragmentation, as has already been
done with the other head shields.

30 Journal of the F.M.S. Museums. [Vol. X,

When the anatomy of the Hydrophids comes to be
better known, a considerable regrouping of many of the
species will surely be necessary. T. annandalei should then,
I think, be placed by itself ; until this is done it may as
well remain where it is.

The variation in my series is as follows : — Nasal shields
usually divided, either longitudinally or transversely, into
4, 6, or 8 pieces ; praefrontals usually divided into 3, 4 or 5
pieces ; frontal and supraoculars entire ; parietals separated
from each other, and sometimes from the frontal, by small
scales ; supralabials irregularly divided, sometimes entire ;
anterior chin-shields well developed in 1 example (No.
3888) , absent in all the others.

62 to 73 scales round the neck, 74 to 91 round the body,
ventrals 320 to 368.

Dentition. — Posterior maxillary, 6 ; palatine, 8 ; ptery-
goid, 20 ; mandibular, 16 (1 specimen examined).

The type locality of this snake is Patani, and the
specimens from there are said to have from 90 to 100 scales
round the body. As will be seen by the annexed table,
none of my series has so large a number.

Enhydrina valakadyn (Boie).

Enhydrina valakadien, Bouleng., Cat. Sn. B. M., p. 302 (1896) ;
idem. Fauna Malay Pen., Rept. and Batr., p. 193 (1912).

Enhydrina valakadyn, Stejneyer, Herpet. Japan, p. 437 (1907) ;
Wall, Mem. Asiat. Soc. Bengal, II (8), p. 191 (1909) ; N. de Rooij,
Rept. Ind. Aust. Archipel., II, p. 221 (1917) ; idem, J. Bombay
N. H. S., XXVI, p. 803 (1919).

Enhydrina valakadyn is one of the most widely dis-
tributed, and without doubt the most common, of all the
sea snakes. It has also been accorded a greater range of
variation in the number of its scale rows (40 to 60 round
the neck, 50 to 70 round the body) , than any other known
species.

This is true, but only when the species is considered
as a whole, and without regard to the region whence the
individuals have come. The very large series that I have
been able to examine from the Malayan region shews that
the variation in any one locality is considerably less — about
12 to 14 — or, if the sexes are considered apart, seldom more
than ten. The number of specimens that I have seen from
the Indian coasts is not great, but in so far as they go they
agree entirely with the Malayan examples in this respect.

I gather also from these Indian specimens, that the
maximum average number of scale rows obtains in that
region ; and I find too that in the disposition of certain head
shields they differ from the Malayan form.

Tentatively, therefore, I recognize two forms, wliich
are as follows : —

An Indian form.
Forma valakadyn (type locality, Tranquebar). 45 to
60 scales round the neck, 55 to 70 round the body ; ventrals,

1920.] Dr. Maixolm Smith : Sea Snakes. 31

240 to 320 ; praef rentals usually in contact with the supra-
labials, 3rd and 4th labials usually touching the eye.

Habitat. Arabian Sea and coasts of the Indian Penin-
sula.

A Malayan form.

40 to 55 scales round the neck, 49 to 66 round the body ;
ventrals 239 to 292 ; praefrontals usually not in contact with
the supralabials (80%), fourth labial only touching the
eye (60f^c).

Habitat. Coasts of the Malay Peninsula, Siam and
Cochin China.

With this latter form I am able to deal ver\' fuUy.
Altogether I have examined about 140 examples ; 60 of
these are from the Straits of Malacca, and the remainder
from the seas East of the Peninsula.

It is possible, if one cares to go more closely into
detail, to separate this form again, the dividing line between
them being the Peninsula. As, however, they differ only
In a slight variation in the number of body scales without
alteration in the head shields, it is preferable to consider
them together. The actual variation is as follows : —

Straffs of Malacca.

43 — 55 round the neck, 52 — 66 round the body. Ven-
trals, 239—278.

Gulf of Sum.

40 — 52 round the neck, 49 — 62 round the body. Ven-
trals, 239—292.

In the whole series the praefrontals fail to touch the
supralabials in 112 examples. In nearly every instance this
occurs on both sides. In the same series the 4th labial only
touches the eye in 85.

Females on the average have from 3 to 4 more scale
rows round the nedc and body than males. I find the sexual
variation as follows : —

Straits of Malacca. — Males, 13 — 18 (av. 45) round
the neck, 52—60 (av. 55) round the body, ventrals, 239 —
270. Females, 45 — 55 (av. 49) round thQ neck, 54 — 63
(av. 59) round the body, ventrals, 248 — 278.

Gulf of Siam. — ^Males, 40 — 48 (av, 43) round the nedt,
49—59 (av. 53) round the bodv, ventrals, 243—292 (av.
264). Females, 42—52 (av. 46) round the neck, 51—62
(av. 56) round the body, ventrals, 239—287 (av. 260).

Abnormalities in this form are not uncommon, and
such faults in development as partially divided frontals,
fusion of the frontals with praefrontals, of oculars with
labials, and oculars with each other, occur frequently.
Fragmenlation of the parietals to f0rm a small interparietal
occurs in about 50<^r.

32 Journal of the F.M.S. Museums. [Vol. X,

Colour. — The colour of specimens from this region
presents nothing that has not ah-eady been described. Four
individuals, however, deserve comment. No. 2045, although
adult, is still marked with narrow jet black dorsal bars in
the posterior three-quarters of the body. Nos. 2047, 2048,
3856 have a broad black irregular band along either side of
the body, a narrow ventral band, and irregular black dorsal
spots. All three are from the same locality.

Distribution. — On both coasts of the Malay Peninsula
this form is extremely common. At the head of the Gulf
it is somewhat less numerous ; along the East coast of the
Gulf it is comparatively rare, and beyond Cap St. Jacques it
has not yet been recorded.

Breeding. — Young are born in the Gulf in March and
April. Until recently I had never seen more than 5 embryos
to any female. Last year, however, I obtained one with 18,
five in one oviduct and thirteen in the other.

Dentition. — Posterior maxillary, 3 ; palatine, 6 — 7 ;
pterygoid, 14 — 17 ; mandibular, 15 — 16 (9 specimens
examined) .

Enhydris hardwickii (Gray) .

Enhudris hardwickii, Bouleng. Cat. Sn. B. M., Ill, p. 301 (1896) ;
idem, Fauna Malay Pen., Kept, and Batr., p. 193 (1912) ; Wall,
Mem. Asiat. Soc. Bengal, II (8), p. 247 (1909) ; Smith, Journ.
Bombay N. H. S., XXIII, p. 787 (1915) ; Ouwens, De voornaamste
giftslangen van Nederlandsch oost-indie, pi. Ill (1916).

Lapemis hardwickii, Stejneger, Herpet. Japan, pp. 401 and 435
(1907).

This is a common species in the Gulf of Siam and along
the coast of the Malay Peninsula, and I have been able to
examine a large series. I have specimens also from Cap
St. Jacques, Cochin China, and no doubt it extends north-
wards up the coast of Annam, as it is said to be common
along the Western shores of Luzon. Males appear to be
far more numerous than females, the proportion in my
series being three to one.

In the number of scales round the body, the range given
by Boulenger is certainly too limited, particularly in the
number round the middle of the body. My specimens
shew a much greater variation, and in this respect are more
in accordance with the figures given by Wall. The species
is so distinct that it cannot be confused with any other form.

Sexual variation is well marked, the males having the
lower count both in body scales and ventrals. Specimens
from the West Coast of the Malay Peninsula do not appear
to differ, either in scalation or in colouration from those
found in Siamese waters.

The following table is drawn up from about 230 ex-
amples : — •

Males.
Round the neck :--23 to 29, usually 25 to 27." Round
the body :— 25 to 35, usually 27 to 33. Ventrals :— 114 to
152.

1120.] Dr. Malcolm Smith : S^fl Sna/res. 33

Females.

Round the neck :— 27 to 35 (usually 29 to 33) . Round
the body :— 33 to 41 (usually 35 to 37) . Ventrals :— 141 to
230.^

That marked sexual variation existed in this species
was observed long ago by Boettger in working on Philippine
specimens, (Zool. Anz./p. 395, 1888), but his observations
seem to have been overlooked by most authors in writing
since.

Boettger's remarks apply chiefly to the ventral shields,
and the figures he gives (I quote 3tejneger, p. 401) are 135 —
168 for males, 186 — 237 for females. I cannot but think
that had he worked on a larger series — he had only 31
specimens — the difference which he found between the
sexes would have been less marked. Apart from this, his
figures, both in range and average, are considerably higher
than what is recorded by any other author for this species.
It looks indeed as if the Phillipine form differed from the
others, although it is possibly due to the different method
employed in counting these scales.^

Colour. — Greenish or yellowish olive above, whitish
below, with from 35 to 50 dark grey or olive dorsal bars,
tapering to a point on the sides. Variations to this are
frequent. The dorsal bars may be continued round tlie
body as complete bands, a form seen most frequently in
juveniles. A narrow black ventral stripe is sometimes
present, or less frequently, a broad irregular ventral band.
Coalescence of the dorsal bars occurs in adults, and in
some the entire back is of one uniform colour. One speci-
men (No. 2460) is uniform slate grey throughout. Young
ones have the head black, with or without yellow markings
across the snout and along the sides of the head.

Specimens from Koh Kong are, as a series, greyer and
darker than those from the head of the Gulf, and are more
prone to have ventral stripes and bars.

Ouwen's coloured figure is an excellent representation
of many examples found at the head of the Gulf.

Variation. — Fission of the second supralabial to form
a pseudo-loreal is not uncommon. 41 scales round the body
occurs in 2 examples only, and in one of these (No. 3883),
the ventral count is 230, the next number in sequence to it
being 203 (No. 1391).

' Ventral counts are very tedious, and the figures given here
are drawn mainly from specimens obtained in the Gulf of Siam.

"The ventral shields of Enhijdris are very irregular in their
disposition, sometimes being broken up, with odd scales interposed
here and there, sometimes missing altogether. The method I have
used has been to control the count by means of the adjacent row
of body scales, which, being uniform in their sequence, indicate
what the correct ventral count should be. •

34 Journal of the F.M.S. Museums. [Vol. X,

The ventral spines of the males appear to be longer
and larger in individuals from the head of the Gulf, than in
those from any other locality 1 have examined. Possibly,
being a sexual character, they increase in size in the breed-
ing season.

Dentition.— Posterior maxillary, 4 to 6* ; palatine, 6 or
7 ; pterygoid, 17 to 20 ; mandibular, 14 or 15 (9 specimens
examined) .

Breeding. — In the Gulf young are born in April and
May, from 2 to 5 being produced. In length they vary
from 250 to 300 mm.

Aipysurus eydouxii (Gray).

Aipiisnriis eudoiixii, Boulenger, Fauna Malay Pen., Rept. and

(1909) N. de Rooij, Rept. Ind. Aust. Anhipol. TT. i). 219 (1917).

Gulf of Siam, 11 exs.

In three examples the praefrontal is divided ; in one
the 3rd and 4th supralabials touch the eye on both sides.
The ventral keel is variable ; in four examples it is poorly
developed ; in three others each keel in the fore-part of the
body bears a strong spinose tubercle, and there is a series
of small tubercles along the adjacent row of body scales
for nearly the same distance.

One specimen was caught some 20 feet above high
water mark, and in life had a rich slate-blue irridescence.

Colour. — Yellowish, with from 44 to 55 dark olive

dorsal bars, which taper to a point on the sides and are

usually confluent vertebrally. Head dark olive ; entirely
black in the young.

* Boulenger in his description of this genus, gives the number
of teeth behind the poison fangs as from 2 to 4. I cannot find any
of my specimens with less than 4,

II. ON A COLLECTION OF PLANTS FROM

PENINSULAR SIAM.

By H. N. Ridley, C.M.G., F.R.S.

The plants dealt with in this paper were collected by
the Federated Malay States Museums during a general
biological expedition, extending from January to March
1919, to the Islands and West Coast of Peninsular Siam
between Lat. 7 and Lat. UN.

Hitherto very little collecting has been done in this
area though Mr. C. Curtis collected at one time in Puket,
Trang and Pangnga while Renong has long been a favourite
centre for orchid collectors. North of this region lie the
Mergui Archipelago and Tenasserim, the floras of which
were extensively collected by Griffith and Heifer.^

The typical lowland Malayan flora, that of the dense
wet forests of the Malay Peninsula, disappears rapidly as we
reach the dryer regions of Kedah, Setul and Perlis, where
it is replaced largely by South Burmese and Siamese plants ;
as we go still further north Malayan plants become again
fewer but it is clear that many have contrived to push their
way through the dryer regions into the northern parts of
Peninsular Siam and into Tenasserim.

Two instances in the present collection are
Pentaphragma begoniaefolia and Cyrtandra bicolor, both
of wmch find their furthest limit here. Well represented
in southern Malaya the species of these two genera become
more scanty the further north we go until they disappear
in this region.

The coUection is remarkably strong in Acanthaceae
with one new genus, and a number of new species.

Acanthaceae are comparatively rare in the southern
Malay Peninsula becoming more abundant in the dryer
northern region. The occurrence so far north of Thottea
(Aristolochiaceae) and of the common southern
Bromheadia palustris (Orchidaceae) in Takuapa, its most
northern limit, are important extensions of range.

Among the most interesting novelties are the fine
Capparis Klossii ; Eloeocarpus tectonaefolius, only allied
to a Javanese species ; the stiff -leaved Canthium trachy-
style ; Vallaris macrantha, with unusually large leaves and
flowers for the genus ; the new genus of Acanthaceae,
Antheliacanthiis, remarkable for its small almost regular
corolla ; Xyris tuberosa, with its remarkable rhizome of
globose joints ; and Carex mapanifolia, with its dense
spikes and broad leaves, allied to C. Helferi of Tenasserim
and C. scaposa of China and Cochin-China.

I Dr. A, Keith collected in Bangtaphan, South-western Siam (between
the latitudes of Renong and Mergui) in 1890-1, and his specimens form part
of the material on which are based Mr. Ridley's botanical papers in the
"Journal of the Straits Branch Royal Asiatic Society," No. 59, July 1911,
pp, 15-234 [C.B.K].

SOME ACCOUNT OF THE JOURNEY ON WHICH

THE PLANTS WERE COLLECTED.

By C. BoDEN Kloss.

All the islands mentioned below are near that part of
the west coast of the Malay Peninsula which is here called
Peninsular Siam, i.e., that portion south of the pass across
the Isthmus of Kra between the head of the Pakchan Estuary
and Chumporn Town and north of the borders of the Malay
States of Perils, Kedah, Perak and Kelantan.

We^ arrived at Pulau^ Mohea from Penang on February
1st, 1919, and left on the 3rd.

The north and south islands are each about a square
mile in area and between 500 and 800 feet high and are
separated from each other by a narrow channel. They lie
in about 7° 13' N, some 18 miles west of the coastal island
of Telibon which protects tlie mouth of the Trang River.

From its south-east point west-about to its northern
end the south island is steep-to, its western side consisting
mainly of high precipitous cliffs : to the east and south
it slopes fairly gently and along these shores are several
sand beaches with broad reefs in front. The northern
island is lower and apparently consists of three hills sloping
to the S.E. and joined by sandy necks : all along its south
and south-east sides is a sand beach and reefs : the west
and north sides are high and steep and there are a couple
of rocky coves.

The islands were exceedingly dry and there were no
flowers but some fairly big timber, wild bananas,
Licualas ( ?) and Caryota palms. They are largely forested
on their eastern sides.

The only water found was in two little soaks on the
south island : the western seemed stagnant, the northern was
running in the sand. The sea round the islands is beauti-
fully clear and fish were numerous : there is a fine coral
reef in the channel. There are no inhabitants but the
islands are visited occasionally.

We lay at anchor off the south-east entrance of the
channel in 8 fathoms. Vessels should approach no nearer
for even in 4 and 5 fathoms there are coral heads which
show above water at low tide. A passage through the
Strait could be made with care by keeping nearest the
south side.

North of Pulau Mohea are some islets — the Pilgrims
and Koh Ma. The former are of limestone ; the largest,
shaped like a boot, has some grass and shrubs. Koh Ma is
apparently of sandstone and is largely covered with vegeta-
tion.

We passed these on February 3rd on our way north
to Koh Pipidon situated in lat. 7° 46' N and about 13 miles
from the mainland and 20 miles from Junk Seylon to the
west. It is the largest of the Vogels, high and wooded,
about 4 miles long and two broad. There is a deep bay
on the northern side and another, nearly land-locked, in the
north-west coast (not shown on the charts). Tliese are
separated from each other by a narrow nock of land which
connects together the two main portions of the island lying
east and west.

South of Pipidon is Koh Pipithall, a long narrow, nortli
and south ridge of limestone with, apparently, a deep fiord
near its middle. Many of its summits arc rounded but its
sides are precipitous and the north extremity is absolutely
perpendicular.

We anchored in the nortli-west end of the south bay
of Koh Pipidon (also known as Pulau Bri-bri) in 8 fathoms.
The western part of the island is a long ridge of limestone
— like Pipithall, very finely coloured white, grey, red, brown,
but more clothed with vegetation ; the eastern portion is of
other formation with more gentle and forested slopes. The
two are joined by a neck of low sandy land north of which
is the newly-noted bay now in process of being filled up
with sand. A steep limestone mass rises to the north of
its entrance while there is a small mangrove swamp inland
at its south-western head. On the east side of the bay the
forest is very thin and patchy.

In south bay beneath the limestone cliffs which form its
western side is a flat reef of sand and coral, dry at low tide,
which rises fairly steeply : the head of the bay is clean white
sand, fairly deep ana shelving and on the eastern side a
steep- to reef juts out parallel to the limestone cliffs for some
distance : anchorage is between these two.

The beach which runs all the way along the south side
is of fine sand, interrupted in two or three places by out-
crops of rock. East of the first of these lie a few huts
which form a temporary settlement of Sam-Sams who visit
the island for fishing : 2-300 yds. behind the hamlet is small
well of bad water ; this was the only water we found on the
Island.

In the forest covering the flat neck were numerous
giant CoUocasias 12—14 ft. high with stems a foot through ;
the roots are used as food.

The mangrove swamp which is the last indication of
part separation of the east and west higher lands is filling
up like the north bay where there is now anchorage for
small craft only under its north-east point.

The wliole island was very dry and except for a little
Hlacnflower woody plant {Pseaderanthemiim creniilatnm) ,
the only blossoms seen were in the beach vegetation.
Gycads, Licualas and other palms are common.

68 Journal of the F.M.S. Museums. [Vol. X,

With easterly winds there was a good deal of swell in
the south bay but the water was always beautifully clear —
shiny pale green over sand and reefs, darker green in greater
depths.

On the 6th we proceeded to Puket in Junk Seylon Island
and were detained there until the 10th awaiting arrival of
a fresh supply of coal from Penang, but the hospitality of
Mr. J. F. Johiis, H.B.M. Vice-Consul, rendered our stay very
pleasant.

On the 10th we left Puket for Pangnga at the head
of the Gulf of Junk Seylon. The wind was fresh but sea
quite smooth as we steamed north along Palau Panjang a
large island in the middle of the Gulf. Tharua on Junk
Seylon, which we soon passed, was once a Portuguese settle-
ment. In this part of the gulf' there are only two limestone
islets, Pipi and Sot, but nearer the head limestone becomes
dominant and is wonderfully picturesque northwards of
Koh Chanak. It occurs as islets of all shapes and } izes —
icebergs, towers, spires, clift's, serrated ridges, roundec hum-
mocks and overhanging knobs — partially covered with
greenery but showing surfaces of white, grey, buflf, red,
brown purple and slate, while the sea at its bases lies stiU
and deep, dark from shade and reflections.

At the head of the Gulf are wide shallows whence rise
Koh Mak, a low island which is a guiding mark for the
mouth of the Pangnga River and, further north-east, two
limestone blocks between which lies the course to Paklao.
We kept on northwards passing twenty yards west of the
little Pulau Chetek and, stopping for a minute or two at
2.20 p.m. off the village at the seaward end of Pulau Pungi
to engage boats for the journey up river to Pangnga Town,
entered the river between tall limestone peaks and anchored
at 3.40 p.m. off the customs house. Hereabouts the river
runs tlirough mangroves and there are numerous waterways
but many great limestone masses tower above the swampy
level and relieve and beautify the scene.

On the 11th we left for the town in a dugout, some of
which are here very large indeed. It took about an hour
and a half to reach the landing place, passing all the while
through mangroves above which rose limestone hills like
icebergs from a sea. One of these, a mile or more north
of the custom house, bears a likeness to an elephant and is
called Koh or Kao Chang — I don't know which : the one
means " island " and the other " hill " and both would
apply.

At the landing steps, where lay several small cargo
boats, there is a double row of small shops, mostly Chinese,
and the road, rough but partly metalled, runs inland half a
mile till it meets another crossing at right angles ; the left
branch going to Kasom, the right to Pangnga : at the junc-
tion is the Governor's house of white-washed stucco. An
attempt has been made at an avenue. The road runs first

1920] Ridley : Peninsular Siamese Plants. 69

through rice fields with ckimps and hnes of Borassus pahns
and then turning towards the left traverses undulating coun-
try for a couple of miles before reaching the town, passing
various houses and huts with, on the right, a good police
barracks in a line grassed enclosui'e and a gaol and, on the
left, a post and telegraph office.

The present town is almost entirely of wood and palm
thatch for the old town beyond it and nearer the river was
burnt down about a year ago and the substantial brick walls
and cement floors are all that remain — no attempt apparent-
ly having been made at rebuilding.

Beyond the old site lies the river — a clear shallow
stream in a very broad sandy bed probably full of water in
the summer season. The further side is fringed with a tall
feather-like bamboo concealing houses and gardens and
beyond rises a lofty precipitous range of limestone which
is less regularly duplicated on a smaller scale on the near
side of the stream. Between these two the main road runs
on through fruit orchards and rice fields (divided into un-
usually small units) to Takuapa. Where the town street,
which is only a branch, joins it stands a wat or monastery
in charming grounds.

The shrine is a very plain building with an iron roof
and contained three well gilt images : to the large central
one a white elephant is offering a bottle of beer lifted high
in its trunk. The Abbott's house is a pleasant attap building
and there is also a good wooden bungalow and a large un-
walled shed, while scattered about in the shade are sitting-
platforms. Shady trees, red acalyphas, slender areca palms
and grass lawns make a pretty foreground to the limestone
cliffs which shelter the spot. The Abbott came to talk with
us and sent us glasses of tea : there are too few Siamese
in the town (the population of which is largely Chinese) to
supply sufficient novices to keep the wat in proper condi-
tion : many sick people were refuging with him (influenza) .

Though perhaps I expected rather more after reading
Warington Smyth's description* this is certainly a most
charming place, especially the pretty and restful wat. One
perhaps looked to find the cliff's rather more dominant ; but
though they are very beautiful and striking they do not
overshadow the town.

Fish, vegetables and fruit were for sale and one or two
Indian cloth-merchants had shops : there is now no rest-
Iiouse. On tlie road ply two-seated gharries drawn by
sturdy little Bandon ponies in excellent condition wearing
well-padded collars and saddles.

We got back to the launch at 2.30 p.m., coming down
at dead low tide with many sand and mud banks exposed
along the edge of the mangroves : in the fairway there are
rocks and heavy snags at one or two places so if small

vessels attempted to proceed above the Chapsi (or customs
house) they sliould do so with great care and local pilotage.
At the landing place is a small wharf and a stockyard : at
the customs house is also a small wharf and a dozen houses.
Plenty of water was to be had nearby from wells.

We left at sunrise, the early rays tinging with beautiful
colours the limestone hills to westwards some of which
come sheer down into the river. Coming out of the river
mouth Pulau Fungi, seen end on, looked like a huge thumb
sticking out of the water. Behind it is a fiord-like channel
between limestone chff s which leads to Kasom but the usual
way is more to the westward along the mangroves as runs
the route to Pangnga to the east. As we turned west into
Pakra or Pak Phra Strait between Junk Seylon and the
mainland we got our last view of the weird shapes of Koh
Chanuk and the adjacent islets. Some of them have been
embraced by low expansions of land and are now part of
the Peninsula. The softer hilly scenery of the Strait is
pretty — forest, green and yeUow grass and brown burnt
patches. Most of tlie bays along the shores are shallow
and in some of them are stretches of large trees growing
in the sea {? Sonneratea sp.). There are many fish traps
with their attendant wings of stakes.

At the point where the road and telegraph line from
Puket reach the shore there are some houses and a large
sala (rest house) : also here and there along the shores of
the strait are solitary, or little collections of, houses : there
are a few coco-palms. A mile or two from the western
mouth of the straits we stopped to get a pilot off a pretty
little peninsula with a police station and some shops beneath
tall Casuarinas and Barringtonia trees and a fleet of boats
anchored behind it.

We might have done without the pilot as the shoals at
the mouth could be distinguished though the tide was high :
the northern bar was indicated by the breakers and the
southern, which is outside and overlaps, it, was to be located
by its colour. The shores of the exit are low and sandy
and lined with Casuarinas and thereafter, until the hills
forming the entrance to Klong Bagatae or Tung Pran in
Takuatung were reached, we steamed in beautiful calm blue
water along a practically unbroken sand beach fringed with
Casuarinas and backed with forest ; at intervals passing
houses or hamlets with boats drawn up before them on the
shore.

Lem^ Thom Tjob (Lat. 8° 33' N.) the western extremity
of the long point sheltering Klong Bagatae, is 500 ft. high
and covered with wind-swept forest : a reef extends outwards
from the lower northern point. On the opposite side of the
Klong (river), Lem Lajan to the eastward is hilly with
many rocks at its foot but thence sand and Casuarinas run
southward to Ban'' Tapmo. We steamed in beyond the
last to look for a good collecting shore but everj^vhere

higher up the inlet were mangroves and sand or mud
exposed i^oals apparently blocking up much of the shallow
head : so we turned back and anchored in 5 fathoms
a mile and a half within the western cape near a little beach
and some coco-palms. We had a few visitors — Malay-
speaking Sam Sams.

In the afternoon I walked to Lem Lajan which is on
the boundary between Takuatung, in which we were, and
Takuapa to the north. It lies about Sy^ miles north of
Ban Tapmo over firm sand or short dry gi'ass among the
Casuarinas. The forest behind shaded rather thorny under-
growth : many of the trees bore orchids but their flowering
season was over except for one pale crimson species.
Adjoining the hilly country south of Lem Lajan is a big
sandy lagoon backed by mangroves and the tide was pouring
into this along a channel through the beach : a reef with
rocks borders the shore.

The western point is a low hill covered with open
forest : flowers were few, the most conspicuous being a pale
pinkish-white one spotted with crimson, borne by a plant
2-4 ft. high (Cystacanthiis pnlcherrimas). Fan palms and
Licualas were common and several species of orchids were
numerous above the shore rocks, but all flowerless. A
swampy depression almost cuts off the point and seawards
there is a curious mud and sand lagoon surrounded by
mangroves and littoral vegetation. Eastwards on the main-
land hills rise to about 3,000 ft. and these come down to the
sea at Lem Lajan and northwards.

Traps with lines of stakes (Malay blat and kelong)
seem to be the only form of fishing practiced. The people
of the village, which is an extensive one, kept to themselves.

We left early in the morning of the 16th February.

There was little to be distinguished for some time as
we stood well off to clear the reefs. Approaching the
secondary or middle entrance to Takuapa Inlet, Pak Kruen,
its southern side was seen to be slightly hilly and in part
grass grown. Inland, more or less easterly, a fine conical
hill or small mountain stood out well. The island north
of Pak Kruen, Koh Pra Tung, is quite low and flat with
Casuarinas along its seaward beach. Koh Gab, the northern-
most of the islands forming Takuapa Inlet is separated from
the last by a very narrow entrance where the water showed
pale green and is high and hilly with long beaches divided
from each other by combs of rock : the shore is backed by
Casuarinas and in a few places are houses or little hamlets :
the northern point, Takuapa, or Kopah, Head (Lat. 9° 16'
N.) is rocky and bordered by a reef. On the mainland
opposite are small forested knolls coming down to the sea
and then a long low stretch with Casuarinas and a few
houses : south of this is a wide inlet and south again the
whole Strait seems edged with mangroves. There are many
hills and ranges inland, some of those visible being perhaps
3 to 4,000 ft. high, as is one near the sea with a good many
sloping rock faces on its south-west side. Within the north

72 Journal of the F.M.S. Museums. 1 Vol. X,

point of Koh Gah is a fine sand beach with some flat grass
land and Casuarinas behind, a mangrove swamp and some
dense scrub. A mile or two farther south, concealed by
mangroves, lay a small Chinese village in a bight between
hills whence comes an excellent stream of good water in a
rocky bed. The hills above are covered with penetrable
forest in which meander paths connecting oil trees which
after tapping are caulked with bundles of soft bark jammed
into the holes. Here in the hills are some very pretty rocky
water-holes in the bed of the stream : very few plants
were in flower. Near the mouth of the stream were two or
three houses belonging to Chinamen who have married
Siamese women : they have good vegetable gardens, areca
palms and pepper plots.

On the 17th we moved up channel and anchored off* the
northernmost little hillock on Koh Pra Tung, passing on
the way the small exit which seemed quite clear and without
breakers though there were rollers across the mouth. There
is a large space in the interior covered with Melaleuca trees.
On the mainland opposite much the same feature occurred
— a large plain about 10 ft. above high-water level of dry
white sand over which grew grass and scattered shrubs, very
thick at their bases which were clothed with much moss and
immense numbers of orchids. This sand was pure white
and crunched exactly like frozen snow when walked on : it
looked like snow too. Here occurred Bromheadia palustris
while several of the bushes bore pretty pale green or white
flowers {Holarpena pauciflora, Eugenia zeijlanica, etc.).
Elephants were said to be common inland near the moun-
tains.

On the 18th we reached Koh Jam Yai (Big Jam Island)
at 1 p.m. and after passing along a rocky shore in depths of
3 fathoms anchored in a shallow bay on the south-east side,
south of the summit (700 ft.), where there is a neck of low
land behind a considerable reef. Along the north-eastern
part of the island runs an almost continuous beach and the
land is low, dipping from the central hill which shows faces
of rock. Koh Jam Yai (Lat. 9° 30' N.) is about 3 miles long
and one wide and about 5 miles from the mainland.

On the 19th I rowed across depths of 3 — 5 fathoms ;to
the west side of Koh Jam Noi (Little Jam Id.) : here are
no beaches but patches of sand above rocks : the sides were
steep with much large bamboo above them. The Sugar
Loaves to the north are pretty little hilly islets with sand
spits and Casuarinas : we found depths of 4 — 7 fathoms
between them. On Feb. 19th we reached Delisle Island,
about 5 miles long by 2 wide. There are two attractive
bays on the west side, in the southern a few houses, but
the coast is a foul one with many rocks off'-shore : a hill
forming the western point of the island separates the bays.
Rounding the north point we found sand beaches running
for a mile or so towards the eastern point and anchored
in 3 fathoms otf the first (Lat. 9° 45' N.) . A broad flat reef
and sandbank bare at low springs made landing difiicult

but fiu'ther down, beyond outcrops of rock, the southern
beach seemed cleaner and steeper. The land m our neigh-
bourhood was partly swampy with many rattans and palms,
partly dry and sandy. The forest was not lofty. We found
no water but it was to be obtained on a point, or island, to
the east. The eastern shore of Delisle Id. is low but a hill
rises near the south. On the mainland opposite were high
hills many of them looking rather bare and these with the
smooth green sea and the neighbouring islets made a pretty
scene.

We left at 11 a.m. on the 20th Feb. and steering round
the west side of Saddle island, where there are attractive
Casuarina-bordered beaches contrasting with the mangrove-
fringed northern shore; passed south of the Lighthouse and
east of everything else up to Koh Phi (the lighthouse island)
outside Renong River where we anchored. On the south
side of the mouth is a village at the foot of a small hill and
a little farther on the opposite bank is the Customs station
with a well built sea-wall and jetty beneath another little
hill. At low tide the sand and mud banks at the river-
mouth almost close the entrance. Inland up-stream are
mangroves and beyond them a frontal range largely treeless
and brown but assuming beautiful tones in the afternoon
light : behind all are the peaks of the main range covered
with forests.

On the 23rd we paid a visit to Renong town, going up-
stream at low tide. Except that it passed two or three little
hillocks the river winds among mangroves and much mud
and sand were exposed. After a couple of miles we passed
a landing place and row of buildings on our right where
a number of boats and lighters lay high and dry : soon after
we repeatedly found shallow water and had to wait for the
rising tide and after about two miles more the stream,
branching, became too shallow for our boat so we returned
to the landing place, meeting on the way down canoes going
up laden with firewood. On shore we got a 2-pony victoria
and travelling along a fair road, south of which is a wide
plain being worked for tin with dredgers, passed numerous
Siamese and Chinese shops and stalls and in about two miles
reached the beginning of the town proper. Here were
better-class shops, some of brick and stucco, cinemas, post
and telegraph office and a good neat gendarmerie barracks.
We first called at a substantial brick courthouse on an espla-
nade with a pavilion and football ground and then v/ent up
a low hill to the governor's office, a good and large brick
building where we saw an English-speaking official — the
governor being absent. Langsuan on the east coast, we
learnt, could be reached from here in three days on foot
along a track of sorts. Renong town lies long and straggling
between the government quarter and the landing stage and
is of the usual nondescript peninsular type, largely Chinese,
with no particular features ; the most notable being the
house of the old Rajah who governed here before the Civil
Service System was introduced : it stood in a large tree-

74 Journal of the F.M.S. Museums. [Vol. X,

planted space surrounded by walls twenty or more feet high
with a large summer-house over the gate : the roads were
pretty good and there were some fair residences : in the
Chinese stores plenty of tinned provisions were to be had
but there was little fruit. The place was dry and dusty,
larger than Pangnga but not nearly so picturesque.

A few Europeans of the tin dredging company live and
have their repairing shops here and a good deal of Malay
is understood.

On the 23rd we crossed the Pakchan estuary to Victoria
Point in Burma and anchored off the jetty (Lat. 10° N.).
The settlement seems to have grown a little since I was
there twenty years ago. Though with its paths, tree-dotted
grassy slopes and red-roofed houses it looks attractive from
a distance it does not improve with acquaintance — the
bazaar is small and squalid with little stock, the paths are
of clay and very rough and in the rainy season must be very
muddy, and the grass is lallang. But from the Wireless
Station on the ridge the view over sea, islands and main-
land to the mountains is wonderful. A road to Maliwun is
metalled for the first eight miles, beyond it has been aban-
doned and the bridges are down; but it can still be traversed
by motor-cycle in the dry season. The place was in charge
of a sub-divisional officer and a European Inspector of
Police : there were besides a Eurasian preventive officer, an
Asiatic doctor in charge of a small hospital, and the staff
of the wireless installation. No supplies were to be had
but water from wells was good. The surroundings are
beautiful : but as a settlement Victoria Point does not com-
pare well even with such a Malayan Sleepy Hollow as Lumut
in the Bindings.

On the 24th we took in firewood and a pilot at Renong
river and left at 11 a.m. The Pakchan is a fine broad estuary
in the lower part, though interrupted by several islands and
almost entirely fringed with mangroves : inland the hills
rise to some height in places (1,000 — 2,000 ft.) but they are
set far back from the shore and are not impressive: Waring-
ton Smyth's reference to its appearance as resembling a
northern fiord and having an air of magnitude does not seem
justified.'^

There are hardly any signs of population in the lower
part except a few scattered houses and hamlets and a fish-
trap here and there : also there are practically no clearings.

We had no difficulty in proceeding as far as Well Hill
(23 miles) but there we got onto our first shoal and after-
wards we had to sound a good deal — for the pilot proved use-
less— to find sufficient water for the launch which draws
6-7 ft. Above Well Hill there are more signs of hal itation
on both Burmese and Siamese banks : mangroves give
place to Nipa palms while a belt of flat coinitry begins to
border the estuary which now becomes more river-like.
We anchored at the landing place of Namchut or Kraburi,

7 Op cit. II, p. 31.

the principal village of the old state of Kra, now merged in
Renong : a couple of miles ahead on the Burmese side we
could see the police station and dak bungalow of Marang
on a low bare hill.

From the landing stage backed by a few shops a well-
kept bridle path ran through rice-fields, which commenced
right behind the Nipas, to the Muang or town of Namchut.
Less than a mile inland are the office and house of the
Ampurr*^ a neat police station and some shops and houses
whence the track and telegraph wire continue northwards
to Chumpom and southwards to Renong. Beyond the
village is a wat with several wooden bungalows and a large
iron-roofed sala, or resting-place, and on a slight hill above
it a temple with thirteen images of Buddlia. There is a
pretty view from the temple showing the dried-up rice
fields, clumps of fruit trees, bamboo, secondary growth
and distant hills and forest : and the regular and dense belts
of Nipa palms along the river look like raised embank-
ments. We woke next morning to find everything drenched
with moisture and shrouded in a dense mist which did not
disperse until 8 o'clock.

On the 25th we left the launch at 1.30 p.m. oJ^i a rising
tide and rowed up stream sounding as we went. Screens of
Nipa hid the country inland : at about 2^2 miles we jDassed
Marang dak bungalow on its bare hill and about 2 miles
farther up came to the first clear view on the west side —
steep banks of earth with the ground running back sharply
and level, covered with rice or grass. Above Marang houses
become more numerous but many of them are hidden by
the Nipas. At about live miles we came to Mamoh on the
Siamese bank and from thereon the view became more open
over rice fields with houses, low characteristic barns, clumps
of trees, palms, bamboos and partially forested low hills.
At about 7% miles we reached a substantial landing stage
and found a bungalow a hundred yards inshore and also
the termination of a good broad earth road coming in from
the N.E. This place was Tapli : a village lay half a mile
farther up stream and after interviewing the Phu-yai-ban
(headman) we set off on our return journey, arriving at the
launch at 8 p.m.

On Feb. 26th we took the launch up river at low tide
touching once on a rock in mid-stream: anchored at Mamoh
after haJf an hour's journey. From here a track runs to
Tapli in about 40 minutes through small forest, scrub,
fenced-in houses and gai'dens. On both sides of the river this
district is fairly populated and must produce a good deal of
rice : it owns elephants and many buffaloes.

A track southwards runs through ricefields and land
enclosed by bamboo fences, barbed wire and euphorbia
hedges. There is a modest wat on a small hill. The coun-
try, all under rice where irrigable, was now covered with
brown and tawny stubble pleasantly contrasting with the

a District Officer.

palms, fruit trees, bamboos and patches of scrub and jungle
dotted about : in the distance were hills partly forest, partly
scrub-covered. Numerous and large herds of buffaloes
made rambling about nervous work for a solitary white
man. Mamoh contains several Chinese shops. Between
3 and 8 a.m. in the morning a dense shroud of mist always
lay over the country.

On Mai'ch 1st we sent our men and baggage up to Tapli
in a small cargo boat. The Lord Lieutenant of the Monthon
(Puket) was expected and Mamoh had been making a land-
ing-place for his use : unfortunately it did not extend out
to low tide level but ended in mud two feet deep. The Lord-
Lieutenant did not go ashore at Mamoh.

The journey from Mamoh to Tapli takes longer by
water than by land, but at high tide it is a pretty one as the
ricefields come right to the edges of the banks in places.
Tapli is the name of the landing place : the village beyond is
called Ban Wang Tapoh'-'. A fair-sized bridge was being
built over the stream along which it lies. (Klong Wang).

The view from Tapli was very fine — westward across
the river lay ricefields with a few scattered houses and fruit
trees with low hills beyond : northwards the river winds
among flat ricefields coming from low hills many miles
away with beyond them a mountain range of about 2,000 ft.
running S.E. & N.W. Clumps of trees palms and bamboos
diversified the rice lands and in the evening with the low
light shining on the river and the hills a glorious deep grey-
blue or purple the vista was exquisite.

The hills beyond the bungalow were covered with trees
and much bamboo and the undergrowth was very light.
Every morning the heavy white mist lay over the river
valley : the daily rise and fall of the stream was still con-
siderable (8-10 ft.).

Having at length hired eleven elephants for our equip-
ment (the local animals carry a ridiculously small load)
I left TapU on foot at 10.20 a.m. on March 10th affer seeing
the first lot of our baggage well away. For the first five
kilometres to Eakchan village the trans-peninsular road-to-
be ran north through scrub and ricefields fallow under grass.
At the village which is the last for many miles was a police
station and a long bridge over a broad stream between high
banks — the Klong In Song which the road follows, a tribu-
tary of the Pakchan rising in the Central range not far from
the sources of the Klong Tasan, on the eastern side of the
divide, which runs to the Gulf of Siam south of Chumpom.

Thence the road with the telegraph line passes through
uninteresting scrub, first eastwards, then south and again
east until it reaches the main range which is covered with
evergreen forest. The boundary between Renong and
Chumporn is 18 kilometres from Wang Tapoh : the pass
by which the road proceeds is low — only about two hundred

and fifty ft. — and Tasan our next stopping place, lies at the
eastern foot of the lulls 2^/4 kilometres farther on.

Tasan is not a village but only the station of the engineer
of the Railway Department who is in charge of road con-
struction. The latter is at present of earth only and is
impassible in the wet season : the bridges are all of rough
wood and there is a considerable amount of cutting and
embankment : after the first two hours from Tapli there is
a good deal of water (the Klong In Song) along or across the
track.

Tasan lies in a basin into which the elephant track,
following quite a different route from the road, enters from
the south-west. The house of the Engineer, Signor Giacone;
his office, clerks quarters, coolie lines and a vegetable
garden on the flat, make up the settlement. The elephants
took about 6 hours on the journey, I and my boy 3% hours.
We temporarily unloaded into an old shed and I spent the
night with the very hospitable engineer. Next day I set up
the tents and made camp beneath some trees near the station
between the Klong Tasan and a little tributary of good
water and we moved the luggage into it. Deer flies were
troublesome and in the evening a huge species of mosquito
was active. Seven elephants were sent back for the remain-
ing baggage for which shelters were ready and which arrived
next day with Robinson.

The engineer and his household were all ill with fever
from which he had already lost tlu'ee servants. Tigers also
were bad and had recently taken from a stable within 30
yards of the house a pony and a cow. As a collecting
locality, however, the place looked promising though the
walk from Tapli was very uninteresting while the hard open
road and hot sun had been rather trying.

At Tasan we had excellent di*y weather but hot to us —
the shade temperature one afternoon being 95°, though
generally it was about 92° : at daybreak it was about 68 ° ;
but once when it fell to 65° the night seemed very cold.
In the neighbourhood the country is undulating and
nowhere steep : walking in the valleys is easy. There was
a great deal of bamboo in the forest which, fairly dense on
the flat, was sufficiently open to allow moving about with
ease on the hill tops ; much of this bamboo was fruiting.

There was no great abundance of plants in flower nor
were there many orchids : blossom was commonest on
bushes and climbers and on a few inconspicuous little plants.
Clear-water streams were numerous across the tracks and
in damp spots leeches were troublesome while bush-ticks
abounded eveiywhere. The camp was a pleasant one owing
to its dryness and the absence of mosquitoes ; but several
of our men had short attacks of fever. Elephants frequent-
ly passed through Tasan and a few Siamese went to and fro,
but there was no cart traffic.

Twelve elephants having arrived from Chumporn, on
the 28th March we saw a start made with loading-up and

ourselves set off at 7.30 a.m. The road led through forest
(Tamaila 9 kms.) and crossed a number of streams and dry
gullies : at 20 kms. it passed near the end of a long lime-
stone hill — the first met with, though later other isolated
ones cropped up in the plains. Beyond this one got out of
the hills, and bamboo and other scrubs became more fre-
quent on the flat. At 11.07 a.m. came Sep Yuan (24 kms.)
where stood a road-overseer's house on the north bank of
the Klong (River) Tasan wliich flows into Chumporn Bay
though the town itself is on another river, the Klong Kapao,
which has a common estuary with the Tasan.

Beyond Sep Yuan the road is older, broader and very
largely overgrown with short grass — very dry and sUppery.
Houses, fruit trees,- grass land and rice fields border it now
all the way to Chumporn : the " ton-ta " palm (Borassus)
was numerous in the paddy lands ; coco and areca palms
and bamboo lined the road. The houses were of negative
character without distinctive features. Soon after midday
I had had enough : it was now very hot in the sunlit road
(95° in the shade) though the earlier hours had happily been
cloudy : the railway bridge over the Klong Kapao was a
welcome sight and ten minutes later I reached the Chumporn
Resthouse (35 kms. = 22 miles) at 1.50 p.m. Robinson
arrived at 4 p.m. The walk along the hard hot road gave
both of us very sore feet.

Of Chumporn town not much need be said : it is one
of the places where railway travellers to and from Bangkok
have to spend a night (Lat. 10° 30' N.).

It consists in the main of one long street of shops con-
taining tin and iron ware, cotton goods, lamps, food ; a gaol
with a galvanised iron stockade, a new government office — a
long wooden building on piles facing the less ambitious old
one, post and telegraph office and official's houses. A
holiday of 19 days, general at this period of the hot dry
season, was taking its course.

On the 30th, thanks to the kindness of the Governor,
we made a trip down river in a motorboat starting from the
boat-house of the royal rest-house. The river is pretty, its
clear deep green water running between high steep banks
backed by bamboos, palms and fruit trees with houses at
intervals. Nearer the sea the shores fall away and Nipa
palms and mangroves take the place of other trees.

In an hour and a half we reached a large fishing village
at the mouth ; a slack period was on and preparations were
being made for the fishing season : boats were being re-
paired, screens made, nets mended. In the busy se^:Son the
.population is probably a couple of thousand — mostly
Chinese. The boats, viking-like craft, have a high straight
stem, two rudders, raking stern and one very raking mast.

There is a bazaar, a good customs house, small police-
station and a lighthouse on an island. The shores of the
estuary are generally low.

1920] Ridley : Peninsular Siamese Plants. 79

On the 31st March, all our baggage having arrived, we
went by train northwards to Koh Lak, or Prachuap Kirikan,
in S.W. Siam and in that state we collected for three weeks
but the country was so dry and flowerless that no botanical
material was obtained.

I had the assistance of a native collector at Mamoh,
Tapli and Tasan and his statements as to the size and nature
of the plant from which he obtained his specimens may
occasionally be unreliable : colours, however, being noted
from the fresh specimens are correct.

This account is very superficial : it is written merely
to give an idea of the localities visited and worked and does
not attempt to deal with the flora or fauna of those places.
The latter will be recorded in other papers : in this 380
plants are dealt with, of which 59 species or varieties are
described as new.

Apparently what Mr. Ridley means in this report by
" Malay Peninsula " is not the whole of the Malay Penin-
sula, which extends northwards as far as the head of the
Gulf of Siam (Lat. 13° 30' N.) ; but only the southern
portion below Lat. 7° N., i.e., practically the Malay States :
but exclusive of the Malay district of Perils and inclusive
of the Siamese State of " Patani."

The northern limit of the true Malaysian flora, which
covers the southern half of the Malay Peninsula, Sumatra,
Borneo and — to a less extent — Java, and of which the con-
tinental section may be called Malayan, seems to be a line
joining the towns of Alor Star (in Kedah) and Singgora
(at the entrance to the Inland Sea) .

Botanical features confirm what geological investiga-
tions indicate — that this boundary was the coast line of what
was once an island but what has since become the southern
half of the Malay Peninsula. ^'^

I would call this Alor Star — Singgora hue a major
transverse break in the Malay Peninsula and am inchned
to think that there is another between Bandon and Pangnga,
and perhaps Bandon and Trang.

The pass across the Isthmus of Kra, between Pakchan
and Chumporn, to which so much attention has been given,
is a mere dip in the mountain range there and seems to be
structurally and biologically of very little importance.

Mr. Ridley elsewhere calls the flora of Peninsular Siam
the " Tenasserim Flora " and the choice of the name seems
a reasonable one ; for though the area in which it occurs is
politically Siam yet the plants of a great part of that State
are much the same as those of Tenasserim and the flora of
the latter region was by a long period the first to be investi-
gated and known.

80 Journal of the F.M.S. Mnseuma. [Vol. X,

Between the Malayan and Tenasserimese floras there
must be a transition zone, or area where the two floras
overlap and intermingle, though the zone is probably not
so broad as the zoological one between Indo-Chinese and
Malaysian animals since the latter are more adventurous
than plants.

When travelling between Penang and Bangkok by rail-
way I have been struck more than once by the apparant
(for I am no botanist) marked difference in the vegetation
north and south of the Bandon River ; and it may be that as
the Malayan flora extends practically without adulteration
north to about Singgora so does the pure Tenasserimese
flora stretch southwards to Junk Seylon : and that
the area between the Bandon and Singgora breaks
constitutes a true intermediate region which has
derived its vegetation from both north and south ; though
probably for climatic reasons, and possibly because of a
less effective break near Bandon, northern plants are more
numerous in it.

Perhaps we have, therefore, three floras : — a Tenas-
serimese, a Malayo-Tenasserimese and a Malayan one : but
they all occur in the Malay Peninsula.

Not only is there a north and* south difference but there
is also one of east and west : this may be superficial and
unimportant and due to the presence or absence of certain
forms of vegetation rather than to different floras ; but
anyone who has travelled or sailed along both shores of the
northern part of the Peninsula from Mergui to Penang and
from Bangkok to Singgora cannot fail to be struck by the
contrast between the more forested west and the more
grassy and scrub-covered east.

Though perhaps arising from nature of the land surface
these differences should be kept in mind while analysing
the flora as long as collections are few and sporadic.

collected by Wallich on the shores of Tenasserim. It is
given in the Flora of British India as occurring from Chitta-
gong to Malacca. I have not seen anything like it in the
Malay Peninsula, the species confused with it by Bentham

in. TWO NEW SIAMESE PLANTS.

By H. N. Ridley, C.M.G., F.R.S.

I have found the following undescribed species in a
small collection sent me by Dr. F. W. Foxworthy, Forest
Research Officer, F.M.S. They were obtained by a collector
of the Forest Department who accompanied the expedition
of the F.M.S. Museums Department to the northern half of
the Malay Peninsula in 1919 (antea pp. 65-126).

ANONACEAE.

1. Miliusa concinna, sp. nov.

Branches slender, bark dark brown lenticelled ; young
parts pubescent. Leaves rather distant oblong oblanceolate,
blunt or subacute, base narrowed unequally bluntly bilobed,
membranous to subcoriaceous, thin, glabrous or when
young pubescent on the midrib beneath ; nerves fine incon-
spicuous, 8 pairs, 4 in. long, 1-5 in. wide ; petiole hairy or
glabrous, -1 in. long. Flowers solitary or 2 on tubercles ;
pedicel slender, hairy, -5 in. long. Sepals ovate -12 in.

The specimens under No. 3802 differ in being much
more hairy, the branches being densely 50 ft. tomentose,
and the leaves hairy on the back ; «while No. 3820 is almost
completely glabrous, only the young parts being pubescent.

DIPTEROCARPACEAE.

2. Pachyiioearpus grandiflorus, sp. nov.

short acuminate, base narrowed, blunt ; nerves 12 pairs
prominent beneath, reticulations conspicuous beneath, 6 to
8 in. long, 2-5 to 4 in. wide ; petiole thick -5 in. long,
pubescent. Panicle dense, terminal compact, 3 in. long,
4 in. wide, pubescent ; pedicel -1 in. long. Calyx pubescent
mealy, • 1 in. long, lobes lanceolate acute, cleft nearly to the
base. Petals -75 in. long, -25 in. wide, oblong spathulate

IV. NEW AND RARE PLANTS
FROM THE MALAY PENINSULA.

By H. N. Ridley, C.M.G,, F.R.S.

This paper includes a number of new species recently-
received in various collections chiefly made by members of
the Museums Department in the Federated Malay States
and others from a collection made by myself in Kelantan
in 1917 ; together with various emendations of species of
earlier collections which in the course of my work on the
Flora of the Malay Peninsula I have found it necessary
to make.

A small but valuable collection was made on the East
Coast by Mr. I. H. N. Evans, Asst. Curator, Perak Museum,
of which several new species are described, besides which
he added to our flora Securidaca tavoyana, and Celastrus
paniculata from Pahang. The latter is a verv widely dis-
tributed plant, occurring in India and throughout the Malay
archipelago, but curiously has been till now missing from
the Malay Peninsula.

A small collection made by a native employe of the
F.M.S. Museums Department on Gunong Binlang on the
Kedah-Perak boundary contained a number of valuable
additions including a remarkable new Genus of
Rhanmaceae, viz. : — Oreorhamnus.

On the invitation of Mr. and Mrs. Graeme-Anderson
I visited Kelantan in February 1917, and enjoyed their
hospitality for some weeks at Chaning Estate on the
Kelantan river above Kuala Lebir, and on my way back
stopped with Mr. R. J. Farrer at Kota Bharu. The flora of
Kelantan was very little known. I formerly received a
number of specimens and live plants from Dr. Gimlette
at Kuala Lebir, and had landed once in 1889 on the sea
coast near the mouth of the Kelantan river for a few hours.
Near the Chaning Rubber Estate were patches of forest
untouched by man and here I found the flora typically
Malayan, but vdth a good many new species. Here in a
sandy spot in a forest I found a patch of Trichopus Zey-^
lanicus which I had met with many years ago at one spot
in the Tahan woods in Pahang ; otherwise it is only known
from Ceylon.

A day or two at Kuala Lebir gave me a curious
Rubiaceous shrub obviously of the same genus as a dwarf
shrubby plant collected by me at Klang gates and which
I had referred to Xanthophytum Bl. Further examination
showed that it did not belong to Blume's genus and I have
made a new genus Aleisanthia for the two species : it is
allied to the genus Grania. Curiously I found a true
Xanthophytum on the banks of the Pehi river opposite
Chaning Estate, another generic addition to our flora. The
country round Kota Bharu is mostly covered with rice
fields and other cultivations. I noticed here plots of Coleus
tuberosus, a plant seldom cultivates further south. I

ascended the only large hill in the neighbourhood which
was called simply Gunong and added a number of interest-
ing plants from this rather dry rocky place. Near the
village Tumpat was some open heath country, very sandy :
The flora was more distinctly Siamese, and I found here
the Anonaoeous shrub Rauwenhoffia, a typically Siamese
and Cambodian plant. The sandy shores at the mouth of
the Kelantan river were rather disappointing, the chief
•plants there being Casuarina, Spinifex, Dodonaea, and the
usual common sand-hill plants : but I found also a new
species of Waltheria which was very interesting as the
genus is mainly South American, and the only species in our
area (and it is scarce) is W. americana, believed to have
been accidentally introduced into Asia from South America.

I was much indebted to Mr. and Mrs. Graeme-Anderson,
to Mr. Farrer and to Dr. Geale of Kuala Lebir for their
hospitality through which alone I was enabled to collect
the plants of this Uttle known district.

CAPPARIDACEAE.

1. Capparis pubiflora, var. perakensis. King.

This plant is only known from specimens collected in
Perak by Scortechini. I have recently found it again in the
woods surrounding the Chaning Estate on the Kelantan
river. It seems to me sufficiently distinct from C. piibiflora
DC, a native of Timor and Celebes, of which, however, I
have only seen rather poor specimens. The bracts in this
species are broad, soft and woolly, and the flowers much
more woolly than in our species which has also short
subulate persistent bracts quite glabrous. The young shoots
and just opened leaves are thickly pubescent, and the whole
flower bud pubescent but not as densely as in the Timor
plant. I think it advisable to keep it as a separate specites
under the name of C. perakensis.

2. Capparis paniculata, sp. nov.

A long, much branched but slender thorny climber with
very short decm'ved thorns thickened at base and black at
tip • 1 in. long. Leaves thinly coriaceous, oblong base blunt
tip acute, nerves 5 pairs, 5-5 in .long, 2*5 in, wide, petiole
•15 in. long. Flowers in a lax terminal panicle 6 in. long,
peduncle -75 in. long, slender terminated by an umbel of
about 6 flowers ; pedicels -5 in. long, slender. Flowers
white -25 in. across. Sepals rounded, oblong, outer pair
boat-shaped, coriaceous, inner pair larger with a broad thin
margin. Petals oblong rounded connate at base. Stamens
numerous little longer than the petals ; white. Anthers
oblong, short. Gynophore little longer than tlie filaments,
ovary conic.

DIPTEROCARPACEAE.

3. Balanocarpus ovalifolius, sp. nov.

Tree. Leaves thin coriaceous ovate, cuspidate, base
round shortly acuminate, tip blunt, nerves line about nine
pairs, often very inconspicuous, midrib elevate often on
both sides reticulations minute but conspicuous 3 in. long,
1-5 in. wide, petiole slender -5 in. long. Panicles lax,
glabrous, drying black, 2 in. long, rather few flowered.
Flowers considerably larger than in. B. Curtisii. Sepals
imbricate subcoriaceous, glabrous blunt. Petals twice as
long 15 in. long, oblong, blunt mealy pubescent outside.
Stamens 15, filaments short and rather broad ; anthers sub-
globose, appendage hair-like, longer than the rest of the
stamens. Ovary with stout cylindi-ic stylopediujn, glabrous.

Penang : Ayer Hitam at 300 ft. (Haniff 3727, Curtis
426) . Malay name " Pinang Baik."

This plant was originally tentatively assigned to B.
laitfolius Brandis, a Bornean species, by Brandis ; but it
differs entkely in the venation of the leaves which is exactly
that of B. Curtisii. From that species it differs in the
broad ovate leaves and larger flowers apd more oblong
longer sq)als.

STERCULIACEAE.

4. Waltheria arenaria, sp. nov.

Prostrate, creeping shrubby plant 2 ft. long, twigs
slender, tips tomentose. Leaves ovate elliptic, base broad,
edge serrate tomentose, thickly beneath, thinly above when
adult nerves thick elevate 3-4 pairs -5- -75 in. long, '25- -3
in. wide; petiole -25 in. long, stipules Linear. Heads of
flower '3 in. wide, sessile, densely villous. Bracts linear
villous. Calyx obconic strongly nerved, villous, lobes 5
subulate. Corolla -25 in. yellow, petals linear oblong
spathulate long clawed. Stamens 5 with very short fila-
ments connate at base. Style slender stigma penicillate,
pericarp tomentose at top. Capsule smooth brown 1
seeded.

Kelantan in sand on the sea shore beneath the
Casuarinas at Kuala Kelantan. Abundant.

An interesting find as W. indica L., the only other
Asiatic species, is a tropical weed probably like most of
the genus of American origin. It is an erect plant and is
not common in the Malay Peninsula being only known
from Malacca where Griffith collected it.

RUTACEAE.

5. Glycosmis elata, sp. nov.

Tall shrub 6-8 ft. high. Leaves 18 in. long of 4 leaflets
irregularly spaced oblong elliptic 7 in. long, 2 in. wide,
pale beneath ; 5-7 nerved, nerves strongly inarching, petio-
lules "25 in. long. Flowers in short axiUary ]ianicles 3 in.

A very handsome tree, remarkable for the flowers
being in small cymes in the axils of almost every leaf. The
leaves hang down, the flowers standing erect on the spread-

This has been referred to Hodgsonia heteroclita. Hook,
f. of India, from which it differs in its hairy underside of
the coriaceous leaves, much smaller flower with a much
thicker calyx tube and shorter lobes, and its fruit. H.
heteroclita has a pointed red fruit, thin walled. That of
this species is woody, velvety, grey and quite flat at the top
and base. If dropped in water it can be taken out quite
dry owing to its velvety coat. It is called Akar Kapaynng
from the resemblance of the seed to that of Pangium. It
is probable that it is the Trichosanthes Kadam Miquel of
Sumatra, but his description is incomplete.

The much larger leaves and large flowers clustered on

This plant seems to be quite distinct from Miquel*s
species in its diff'erently shaped leaves and smaller flowers :
King's description is taken from the Singapore plant. The
leaves are mostly simple but when the plant grows suffi-

This plant has been confused with the much larger
H. cephalotes, Clarke, which occurs on sea cliffs and banks,
and has very much larger leaflets broadly oblong cuspidate
and much larger panicles and the leaves are not sub-
puberulous beneath. In a plant I got on Penang Hill the
leaflets are oblanceolate, broadest at the top. A plant
collected by Wray (1542) on Ulu Batang Padang at 4,900
ft., may be this but the specimen I have seen is too young
and Wray describes it as a large tree.

This genus lias not been found in the Peninsula before.
The species is remarkable for its having apparently alternate
leaves, the second one of each pair being reduced to a small

39. Prismatomeris Malayana, sp. nov.

P. albidiflora. King and Gamble Journ. Asiat. Soc.
Bengal Ixxiii, 3 (1904), p. 90 : not of Thwaites.

The type of P. albidiflora to which this is referred by
King and Hooker is a totally different plant with a much
larger shorter corolla and large calyx. It is peculiar to
Ceylon, The Indian species also referred here seems to
me to be a difi'erent plant. There is a specimen from Ceylon
in Herb. Kew which somewhat resembles P. malayana but
the flowers are larger : it is not P. albidiflora, Thw.

P. malayana occurs in Cambodia, Borneo and Sumatra
and all over the Malay Peninsula.

Amaracarpus, Bl.

This is a genus of bushes rarely trees, generally foetid
as in Saprosma and Mephitidia with small leaves rather
crowded, small tubular flowers axillary or terminal, one or
2 together. Fruit generally blue, pulpy one or two seeded,
crowned by the enlarged calyx lobes. Some of the species
have been put into Saprosma, and I think Neoschimpera,

42. Lasianthus Kurzii, Hook. fil.

This was based on a plant collected by Wallich in
Burmah, No. 8310, 8311, of his collections. No. 8311 was
written up by him Penang ? and on the strength of this
has got into our Flora : I have not seen any specimen from
the Malay Peninsula. Allied to it, however, is a species
described by King and Gamble in the " Materials " for a
flora of the Malay Peninsula as Kurzii but they seem doubt-
ful about it. It is a native of Singapore : Garden jungle
(Ridley 140) and Pasir Panjang. It seems to me abundantly
distinct in its much more hairy habit, the branches are
appressed yellow-hairy, the inflorescence and leaves also
very hairy. The Burmese plant though not glabrous has
none of this long yellow appressed hair, and the leaves
appear to have been thinner in texture.

43. For the Singapore plant as described by King and

Gamble (Journ. Asiat. Soc. Bengal, Ixxiii, 2 (1904),

p. 119) I pro])ose the name of Lasianliius chryseus,

Kelantan : Chaning on river banks, Feb. 1917.

A very similar plant to this I found at Angkor Wat in
Cambodia, but the leaves in that are rounded at base and
the calyx more narrowly winged. I cannot match either
with any of Bonati's descriptions in Bull. Soc. France Iv. p.

Avicennia.

The Asiatic Avicennias have been very much confused.
Indeed in most works, they are reduced to 2 species only,

1920] Ridley : New & Rare Malayan Plants. 151

A. officinalis, and ^4. alba. In the field however, it is clear
that there are more than these 2 species.

68. Avicennia officinalis, L.

Is a common species with obovatc round tipped leaves,
very nearly glabrous, and A. alba has lanceolate p>ointed
leaves which dry black and are white beneath. Griffith des-
cribed in Notul. iv, p. 189, a distinct plant A. intermedia
which appears (as Griffith suggests) to be a hybrid between
these two species. It has obovate to lanceolate leaves, blunt,
pale puberulous beneath. Fruit rather small, cordate ovoid,
glaucous. It occurs at Malacca, Pulau Jawa (Griffith).
Selangor, Klang (Watson). Dindings, Pangkor (Scorte-
chini) .

69. Avicennia sphaerocarpa, Stapf (ined) .

Is a small tree. Leaves elliptic narrowed to the tip or
round, the base narrowed, whitish beneath, 3 in. long, 1-5
in. wide, petiole winged above '25 in. long. Inflorescence
axillary of 2-3 or more flowers, terminal on peduncles • 30-
•75 in. long, pubescent. Calyx lobes oblong ciliate, silky
• 15 in. long. Corolla I have not seen. Fruit ovoid, round
subglobose, not beaked • 75 in. long.

This so far as I know only occurs in the Malay Penin-
sula in Penang where Curtis collected it at Sungai Penang ;
but it also occurs in Siam, the Philippines and China. It is
a very distinct plant in the small round not beaked fruit and
smaller leaves.

70. Avicennia lanata, sp. nov.

Is a new and distinct species, to which my attention
was called by Mr. J. G. Watson, who has been studying the
species of Avicennia in the Malay Peninsula and made
careful notes of the differences in the species. To a certain
extent it has the habit of A. officinalis, but branches and
leaves beneath are distinctly yellow tomentose. I take the
description below mainly from his notes.

A large tree. Leaves obovate blunt closely yellow
tomentose beneath, glabrous, shining above, ners'es 4 pairs,
3 in. long 1 • 25 in. wide ; petiole wrinkled, pubescent • 5 in.
long. Flowers in cymose heads, in threes in a compound
cyme, axillary peduncle "5- -75 in. long, yellowish, tomen-
tose. Bracts densely tomentose. Calyx-lobes tomentose
outside. Corolla glabrous inside, densely hairy outside.
Anthers dorsifixed elliptic filaments about the same length.
Ovary light green, glabrous but surrounded at the base by
dense tomentum. Style bifid, very short, brown, lobes
erect. Fruit ovoid not beaked • 5 in. long tomentose.

Singapore : River Valley Road (BurkiD and Watson
No. 3793, 3797). Pahang, Kuantan : (Watson 2767).

Mr. Watson notes that while Singapore specimens
attain a height of 80 ft., trees from the coast of Pahang
are small and stunted and there he has never met an example

jl52 Journal of the F.M.S. Museums. [Vol. X,

more than 20 ft. high. The species does not seem to occur
m Selangor.

I would add that the cymes are 2-2*5 in. long. The
corolla lobes strongly decurved and the whole flower very
fragrant. In A. officinalis the calyx lobes are spreading
but not recurved, the filaments much longer than the anthers
and the style long and slender. The flowers have an un-
nleasant smell.

LAURACEAE.

71. Litsea glabrifolia, sp. nov.

A glabrous tree. Leaves alternate, thinly coriaceous
glaucescent beneath, oblong or oblong-lanceolate, shortly
narrowed at the broad base, and blunt at tip, nerves 10 pairs,

slender, hairy, innermost three with oblong stipitate glands.
Pistillode cylindric with a 2 or 3-lobed recurved stigma.

Pahang : Gunong Senyum (Evans).

This has somewhat the habit of L. polyantha but the
leaves are rather thinner and quite glabrous, the umbels
much larger and there is a distinct pistillode. I have only
seen the male plant.

beneath ; nervules horizontal parallel, general surface
areolate 3-3-5 in. long, 1-5 in. wide ; petiole "25 in. long.
Umbels one or more pseudolerminal sessile on a peduncle,
silky -25 in. long, -3 in. across when expanded. Involucral
bracts 4, ovate, silky, rather thin. Flowers about 4, pedicels
silky, lobes 3, ovate round spathulate, 3 inner linear oblong,
silky. Stamens 7, filaments slender, glabrous with no
glands. Anther oblong 4-celled. Pistillode small conic.
Style long but shorter than the perianth with three recurved
stigmas.

Kedah-Perak boundary: Gunong Bintang (nat. coll.

This has somewhat the appearance of an Actinodaphne^
but the leaves are not whorled, the stamens in two flowers
examined were 7 in number. It is quite unlike any Litsea
known to me in the falsely terminal flowers.

V. NOTES ON MALAYSIAN BUTTERFLIES (PART I).

By Major J. C. Moulton, o.b.e,, t.d., m.a., b.sc,

Director, Raffles Museum and Library, Singapcre.

Since the publication ni 1882-80 of Distant's fine work,
"Rhopalocera Malayana,'' very little has been published
on the Butterflies of the Malay Peninsula. Neighbouring
Malayan countries have received a certain amount of atten-
tion ; thus de Niceville listed the Butterflies of Sumatra in
1895 ; Piepers, Snellen and Fruhstorfer have recently
brought out four volumes on the Rhopalocera of Java ;
Shelford (1901-06) and the present writer (1911-15) have
dealt with most of the Butterflies of Borneo. Godfrey
(1916) has listed those of Siam, which includes a small
portion of the true Malaysian subregion.

During the last ten years an important contribution to
the literature on Eastern Rhopalocera has been brought
out by Dr. Adalbert Seitz in his great work "The Macro-
lepidoptera of the World," of which Vol. IX is devoted
to the Rhopalocera of the Indo-Australian region. Up to
the present the Papilionidae and Nymphalidae have been
completed ; the Lycaenidae are being dealt with ; but the
parts on the Hesperidae have yet to appear. There is an
English edition of this work ; the ver>' numerous and
wholly admirable plates add considerably to its value. It
is also up-to-date in its adoption of the trinomial system
of nomenclature.

Until a new edition of Distant's " Rhopalocera
Malayana " is published, Seitz's *' Macrolepidoptera of the
World " must be regarded as indispensable to any student
of Malaysian Butterflies, with whom in any case both works
will long remain in use. I have on this account given
references under each species to these two works ; all other
references have been relegated to foot-notes.

It is thought, therefore, that any notes which will supple-
ment or correct the information given in Seitz's " Macro-
lepidoptera of the World" arc perhaps worth publication
from time to time as they accumulate. The following
notes are chiefly based on the collections in the Federated
Malay States Museums, part of which I have had the
privilege of examining and identifying recently. Although
as 1 understand it, no exclusive attention has hitherto been
paid by the F.M.S. Museums to the formation of any exten-
sive collection of Malaysian butterflies, the collections so
far submitted to me prove of no little interest.

The Director of Agriculture, Kuala Lumpur, forwarded
a collection of Malay Peninsula Danaines for identification.
Additional localities from this collection have been incor-
porated in these notes.

158 Journal of the F,M.S. Museums. [Vol. X,

The Director of the Zoological Museum, Buitenzorg,
has been kind enough to send me for identification a small,
but interesting, collection of Danaines from Java and
neighbouring islands. Two new subspecies from the
islands of Krakalau and Verlaten arc described from this
nialerial.

My thanks are also due to the Acting Curator of the
Sarawak Museum for the loan of Bomean specimens from
that Museum and to Mr. E. J. Godfrey for Siamese speci-
mens for comparison. The collections in the Raffles
Museum, Singapore, have also provided material for addi-
tional notes.

The " Malaysian " buttertlies considered in these and
subsequent notes are confined to a " true Malaysian " sub-
region ^ which, for Museum i)urposes, I regard as those
countries lying between Lat. 10° N. and 10° S. and Long. 95"^
and 120° E., i.e., tlie Malay Peninsula, Borneo, Sumatra and
Java and adjacent islands. An exception is made in the
case of a few bulterllies Ironi S.W. Siani (Tasan, Lat. 10°
30' N., and Hat Sanuk, Lat. 12^ N.), which are included
in the F.M.S. Museums collection. They are of interest
in that some species are insepai'able from Malayan forms,
while others obviously belong to the Siamese-Tenasserim
fauna.

The following new forms and new combinations are
introduced in this paper : —

8a. Danaida juventa Cv. krakaiaiiae subsp. nov.
23. Danaida plexippus I^. plexippus L. connectens f. nov.

^\ true Malaysian subregion, as opposed to a wider area in
which a non-Malaysian element is evident although not necessarily
predominant, e.g. an area including Celebes, Palawan and Slam,
to ail of which countries many " true " Malaysian species extend.

The boundaries for this true Malaysian subregion must neces-
sarily be arbitrary to some extent. For Museum purposes I have
extended the northern boundary to Lai. 10° N., although, as Mr.
Boden Kloss points out, the fauna of the Malay Peninsula between
7° and 10° N. is as much Indo-Chinese in character as Malayan.

BoDEX Kloss, 1918, p. 245, writes : " Malaysian — Pertaining
to the Malay Peninsula, Sumatra, Borneo and Java. Malayan —
Pertaining to the Malay Peninsula, Cf. Sumatran, etc" See also

The nomenclature adopted is that used m Seitz's
" Macrolepidoptera of the World," unless otherwise stated.
The method of printing the subspcctfic name in less pro-
minent type than the generic and specific names was
adopted in mv " Hand List of the Birds of Borneo " ' and
my paper on the " Tlie Butterflies of Borneo.- The reten-
tion of the author's name for a species even when followed
by a subspecitic name was also adopted in those papers.
Both courses appear to me to be an improvement on the
usually accepted method of writing trinomials, and have
since received the official approval of the British Association
Committee on Zoological Nomenclature.

All the species of Danainae now known from Malaysia
are listed in this paper and numbered consecutively from
1 to 52. Under each species all the Malaysian subspecies
are listed but not numbered.

A list of the literature quoted is placed at the end of
this paper. The footnotes refer thereto.

Fam. NYMPHALIDAE.

Subfam. DANAINAE.
Genus Hestia, Hiibn.

The foiu- Malaysian species of this genus fall into two
groups or subgenera : -

«. Wings eloif^J'tt' i»n<l weak ; hind wing with
three irregular dark spots (the outer one
small) in space between costal nervure and

lirst iiut)costal nervule Hestia.

a'. Wings rounded and stronger ; hind wing with

only two irregular spots in costal interspace Nectaria.

le structural differences between these two " groups "
as given l)y Frulislorfer do not ap|)ear to be sulticiently
marked or constant to be of much assistance. The second
subcostal nervule of the fore wing arises as a rule very
slightly nearer to the apex of the ceU in Hestia males than
in Nectaria, but in Hestia females there are some in which
the origin of this nervule is just as far from the apex of the
cell as in the Nectaria species. The second character given
by Fruhstorfer, viz. length of lower discocellular in the
hind wing, is also variable and not markedly distinct in the
two subgenera. The sui)erficial characters given in the
above key, however, wUI serve to distinguish the two
subgenei-a^ quite clearly.

M follow Bingham in using the term "subgenus" for sub-
divisions of a genus, rather than de Niceville who used the term
*' group." Fruhstorfer uses both terms, the latter ranking as of
less importance than the former. The distinction between
(lillerences of " subgeneric " and (lillerences of " group " impor-
tance nmst necessarily be a mailer of personal opinion, probably
I)roductive of more confusion and discord than clearness. In this
paper, therefore, genera, when divided at all, are split into sub-
genera only.

Fruhstorfer distinguishes these two species thus :
lynceus, noticeable for the dense blackish dusting on the
upper side of both wings, while in logani the ground-colour
is lighter and the blackish dusting on the upper side is
reduced. Admittedly these Hesiias are ver>' variable ; so
much so that other writers have regarded lynceus and
logani as but one variable species. Breeding experiments
will alone decide the point, although Fruhstorfer regards
certain differences in the genitalia as " of such decisive
significance that the specific rank of logani cannot be ques-
tioned " {I.e.). Piepers 2 doubts the value of these differ-
ences in genitalia.

' Frulistorfer recognizes another subspecies, H. I. hypata
Fruhst. from the Sulu Islands to the North of Borneo, i.e., just
outside the limits of the Malaysian subregion.

'PiEPERS, 1913, p. 21, writes : "Dr. Henri de Graaf a specialist
in this kind of researches, has investigated microscopically 2.^
specimens from my collection, both light and dark coloured, and
he did not find a single one amongst them whose genitalia agreed
with the figure given of those of stolli, on the contrary they all
agreed with those given of logani, and although considerable
individual differences were observed in this respect it was only
as regards the form of the valvae and valvulae and not to such
an extent in connection with the structure of the principal organs
that the existence of more than out species could be inferred
from it."

referable to lynceus with the exception of one maie in the

Although Fruhstorfer gives Ihe " Malay Peninsula "
as part of the distribution of chersonesia, I suspect that it
is confined to the southern half of the Peninsula : perhaps
not occurring north of Negri Sembilan. Godfrey ^ des-
cribes a very distinct subspecies siainensis from Nong Khor
and Hup Bon in Siam (Lat. 13 N.). Probably the original
continental range of leuconoe has long been interrupted
and the species has died out for some reason or other in
the north of the Malay Peninsula leaving a gap between
the range of (and at the same lime giving rise to) the
present-day subspecies siamensis and chersonesia.

It has been shewn' tlial the subspecies nigriana,
chersonesia and natiinensis, recognized by Fruhstorfer,
are not separable. Piepers' slates that jauana is referable
to mitunensis. I therefore use Fruhstorfer's name cher-
sonesia to cover all these forms from the Malay Peninsula,
Lingga Archipelago, Banka, Borneo, Natuna Islands, Java
and the Kangean Islands (East of Java) .

It is evidently a variable species, but unfortunately rare
in collections. Godfrey's siamensis is remarkable for the
absence of a spot immediately below the cell in the fore
wing between the first and second median nervules, which
is always present in chersones-'a. The double cell-spot in
the hind wing of siamensis is very much smaller than that
of chersonesia.

Genus Ideohsis, Ilorsf.

The only species of this genus found in the Malay
Peninsula is common and well-distributed. The general
pattern of large black spots and blackened veins on vitreous
smoky-white ground-colour makes it easily recognizable,
although if it were not for its smaller and stronger wings,
it might be taken for a Hestia.

Ideopsis has been, until recently, regarded as an inter-
mediate between Hestia and Danaida. Fruhstorfer, how-
ever, compares it to the Hadena-gvowj) of Danaida, and
suggests tliat the larva and pupa, when discovered, will
resemble those of Radena rather tlian those of Hestia. It
is remarkable that the life-history ^1 so common a species
should still remam unknown,

An examination of some 200 specimens from the F.M.S.
Museums, the F.M.S. Agricultural Department and the
Rallies Museum, Singapore, shows that this species is widely
distributed throughout the Malay Peninsula, ranging from
low country to 3,000 ft. and probably higher.

Probably on the wing all the year round, as specimens
in the above collections have been caught in every month
of the year except January, February and October

The species is variable in the size of the wing and in
the size of the black spots. Males and females are equally
abundant.

It is perhaps doubtful policy to give it specific dis-
tinction, as it is obviously the Javan representative of daos.
Unfortunately gaura is the older name, so that ii we are
to recognize but one species in Malaysia, it will bear that
name, while Boisduval's long-accepted name daos will
only cover the Bornean subspecies.

On the other hand tiie separation of the Javan form

the marked dill'erence between Ihe fauna of Java and that
of the three neighbouring countries (Malay Peninsula,
Borneo and Sumatra) which I have designated Neomalaya.^

A common butterfly ranging throughout the Malay
Penmsula from Hat Sanuk, S.W. Siam (Lat. 12 N.), south
to Singapore, Borneo and Sumatra.

Two of the three specimens in the F.M.S. Museums
series from S.W. Siam are certainly not separable from
vulgaris. The third is referable to the Siamese subspecies
persirnilis Moore, wet-season form. Large examples of
this are regarded by Fruhstorfer as an aberration named
avenlina Cramer, which is characterized by the post-cellular
spots of the fore wing being rounded instead of acutely
wedge-shaped. The Siamese persirnilis is similarly dis-
tinguished from vulgaris, but it is a smaller insect than
the aventina figured by Fruhstorf-er.^ In the dry-season
form the post-cellular spots are reduced in both wings.
A specimen from Trengganu in the F.M.S. Museums is an
interesting intermediate between wet-season persirnilis and
aventina. The hyaline areas are rather larger and more
noticeably pale green than in typical vulgaris. In size it
is larger than persirnilis, but not quite so large as aventina.
The application of this latter name to the wet-season form
of both persirnilis and vulgaris is, I think, permissible,
although the dry-season fornis of both are readily separated.
Fruhstorfer records a large wet-season form hyria in
Annam and Tonkin, drft'ering from aventina in having the
hyaline areas whitish instead of green. The wet-season
form aventina thus ranges southwards through Siam and is
known at present from Hat Sanuk (Lat. 12° N.), Tasan
(Lat. 10° 30' N.) and Trengganu (Lat. 5° 30' N).

The Javan form vulgaroides is very doubtfully separa-

The above record from Trengganu (Lat. 6° N.) repre-
sents the northern Umit to the range of this species. It is
not recorded from Siam.

Fruhstorfer suggests that reports of the occurrence of
juventa in Malacca and Perak are possibly due to recent
migration, as the species is typically insular. The occur-
rence of specimens on the east coast of the Peninsula in
no way diltcring from Tioman Island or example" from the
Anamba Islands tends to confirm Fruhstorfer's theory.
Distant {I.e.) recorded one from Singapore. The example
figured by him is perhaps referable to this subspecies,
although the underside is brown rather than black.

Fruhstorfer noticed its absence from Sumatra, but
Rothschild ^ has now described a new subspecies, D. j.
robinsoni, from the west coast of Sumatra. Another new
subspecies, D. j. krakatauae, from the small islands of
Krakatau and Verlaten, between Sumatra and Java, is des-
cribed below.

A single male in the Raffles Museum labelled " Johore "
appears to be typical juventa and possibly comes from
Java. It differs from the above-mentioned examples of
sitah in the yellower shade of ground-colour, i.e. lacking the
pale green tint of sitah, in the dark colouring b'^neath being
brown rather than blackish-brown as in sit(di, m the margi-
nal spots above being smaller and the veins less heav5y
marked with brown-fuscous.

Fruhstorfer describes the " very rare race of the Malay

figure (I.e.) of this species, but neither the figure nor the
description agrees with a long series from the Malay Penin-
sula examined by me. The localities given above are taken
from a series of 84 specimens from the F.M.S. Museums
and 20 from the Raffles Museum. I have since examined
others from Pahang, Kuala Lipis, and Negri Sembilan, Bukit
Tangga (F.M.S. Mus.), and from Selangor, Ginting Simpah
and Kuala Selangor (F.M.S. Agric. Dept.). It may there-
fore be regarded as a comparatively common species in the
Malay Peninsula and well distributed. The rarity of the

females, however, is a point worth noticing, since in the
above series there were only 5 females to 99 males.

The characters given by Fruhstorfer for sinopion are
(i) the narrower vitreous areas and (ii) the almost entirely
black ground colour of both wings beneath, which only
show slight traces of a red-brown tinge. In regard to the
first pomt, the Malayan specimens agree admirably
with the Indian example figured by de Niceville.^ There
are, however, two males in the Raffles Museum, in which
the top posl-cellular hyaline streak in the fore wdng is
reduced to a small dash less than half the length of the
lower post-cellular hyaline streak. The white marginal
dots of the hind wing present a variable feature : a complete
series being present in some specimens, while in others two
or three only are barely visible and in one example they are
absent altogether. Similarly the two small spots between
the median nervules of the hind wing vary in size, and in
some specimens partially or completely fuse with the larger
hyaline spots immediately below the outer half of the cell.

The ground-colour beneath is certainly blackish, but in
many specimens a pronounced reddish wash is very notice-
able. I think, therefore, that Fruhstorfer's sinopion for
the Malayan form must be regarded as a synonym
of plataniston, under which name the Indian form is dis-
tinguished by Fruhstorfer. Evans-, however, retains
Cramer's name melaneiis for the Indian form. Cramer's
species is supposed to have come from South China.
Whether the Indian and South China forms are separable
oi' not 1 do not know. Godfrey records plataw'slon from
Siam. Two examples he sends me from Me Song (Siam)
are certainly inseparable from the Malayan plataniston.
The thirty-six males in the F.M.S. Museums from Hat
Sanuk and Tasan, S.W. Siam, are rather smaller than the
more southern Malayan examples and they might be
referred to Fruhstorfer's dry-season form neopah'a but for
the fact that they are by no means " entirely light red "
beneath. The submarginal dots in these are generally
though not always, purer white than in most of the Malayan
examples.

Frulislorfer states of this subspecies that " only a few
examples have hitherto been found." Thorough collecting
on the mountains of the Malay Peninsula will probably
show that it is well distributed and not uncommon.

Distrih. The species ranges from Kashmir and the
Himalayas to China and Formosa and south to the Malay
Peninsula.

Not recorded in Godfrey's list from Siam, but he kindly
informs me (January 1921) that it has been taken in
Northern Siam at Khun Than 3,600 ft. (Lat. 18° N.) and
near Thaungyin river. The example sent to me from the
former locality is referable to tira Fruhst., which is distin-
guished from the Eastern Himalayan form tytia Gray, by
the absence of a thick red cell-streak in the hind wing.
Fruhstorfer gives Assam and Tenasserim for the distribu-
tion of lira. The longer sub-apical streaks in the fore wing
and the presence of two whitish sub-apical dots in the hind
wing separate this subspecies clearly from the only
Malaysian subspecies, ethologa, which lacks these dots and
has the upper siibapical streaks considerably shortened.

Museums the expanse of wings varies from 75-95 mm. In
some, irrespective of size, the cell of the hind wing is
darkened, in others entirely free from fuscous sc lies. The
smoke-brovvn darkening of the underside is also a variable
feature.

I follow Piepers therefore in recognizing but one form
from the whole of Java.

A very common species ranging throughout the Malay
Peninsula ; extending north through Siam to Burma and
Cochin-China and south to Sumatra and Borneo. Three
distinct subspecies in addition to the typical form may be
recognized ; they occur in ihc Malaysian region :-

D. e. borneensis Staud. Borneo.

D. e. furius Fruhst. Java.

D. e. erycina Fruhst. Nias I.

Fruhstorfer recognizes two subspecies from Borneo —
borneensis from South-east Borneo and Pontianak, terilus
from North Borneo ; both melanic forms, the latter parti-
cularly so, due to the great reduction of the pale green
stripes and spots. As both occur together in the same
localities in Sarawak I prefer to recognize but one sub-
species, borneensis from Borneo,- retainiiii?; terilus as a

form name for particularly black specimens. Sarawak
specimens of this terilus form are practically inseparable
from enjcina from Nias. The two post-cellular streaks are
not quite so obliterated in two Sarawak males, while the
upper cell streak and the two below the cell are more so
in one of them.

Rolhscliild' records a female from the West Coast of
Sumatra as enjx. Fruhstorfer's subspecies maenius for
this part of Sumatra is probably therefore only a melanic
form occurring together with the typical form, which in
Sumatra is apparently inseparable from eryx of the Malay
Peninsula and Siam. The Bornean subspecies differs
consistently from eryx in the general reduction of the pale
green markings and particularly in the upper cell streak of
the fore wing and the submarginal row of spots in both
wings, which are always smaller and less developed.

Central India.

Bingham- notes that de Niceville's ligure • of aylea
is tliat of the northern form melanoides. The Pahang
specimen agrees well with the markings of this figure,
but differs in being smaller with narrower fore
wings. Bingham, however, notices that the wings of
melanoides are longer and narrower than in typical aglea.
Godfrey* records melanoides as widely distributed and
fairly common in Siam. Two Siamese specimens, kindly
sent to me by Godfrey, seem inseparable from Indian
melanoides, although the male agrees with the Pahang male
in being slightly smaller, with the fore wing narrower than
in the Indian male figured by de Niceville. This character
is evidently variable, as in a series of 12 males in the F.M.S.
Mus. from Pulau Condore the expanse of wings varies
from 61-78 mm. The fore wing from anal angle to centre
of costa varies from 19-22 mm. in this series. The only
female from this locaUty is rather darker than the Siamese
form.

It is interesting to note that Criiger^ mentioned D. aglea
in a short description of Malacca butterflies as long ago as
1878. Distant^ threw doubt on the record, and apparently
the occurrence of aglea in the Malay Peninsula has re-
mained unconfirmed until now.

Although de Niceville {I.e.) shows clearly enough that
grammica Boisd. (1836) must be restricted to the Ceylon
and South Indian form which Cramer described as aglea
in 1781 and with which it is therefore synonymous, never
theless Fruhstorfer ^ retains Boisduval's name for the North
Indian form. I follow Bingham,* Evans ^ and Godfrey * in
adopting melanoides Moore (1883) for this northern form.

Subgenus Ravadeba, Moore.
The only species of this subgenus found in the
Malaysian subregion is distinguished at once from all other
Danaines by the canary-yellow discal region of the hind
wing.

A common species found throughout the Malay Penin-
sula, ranging from low country to the mountains up to
3,()()() ft., and probably higher. Apparently on the wing all
the year round.

The typical form also occurs in Tenasserim, Siam,
Sumatra' and Palawan. Other subspecies are recognized,
all occurring in the Malaysian subregion : —

D. a. Philomela Zink. .lava.

D. a. caiilonia Fruhst. Pulau Tello, Batu Is.

D. a. shelfordi Fruhst. Borneo.

Piepers and Snellen regard the Javan form as aspasia.
It is, as recognized by Fruhstorfer, quite distinct from the
Malay Peninsula aspasia and must be known as philomela.
The males have the three large post-cellular patches yellow,
while in aspasia they are hyaline, the lowest and largest
patcli alone being tinged with yellow. This seems to be
a constant feature of distinction in the males. In the female
philomela the post-cellular sub-apical wJiite streaks are
much shorter and broader than in female aspasia.

Tlie Bornean subspecies shelfordi is also well-marked
and distinct.

The males of this subgenus are distinguished by a

The Malay Peninsula species of this subgenus and the
next are distinguished from all the fore-going Danaines by
the fulvous ground-colour of the fore wing. This Limnas

which are fulvous like the ground-colour, not heavily
defined in black as in the species of the next subgenus,

pore male, except that the white expanse, the hind-marginal
row of white spots in the hind wing and the two white
spots in the outer orange-brown region of the fore wing
are more developed.

The record of the dark brown bataviana in Singapore
and Kuala Selangor (1 9 ) is of interest in view of its
occurrence also in Western Sumatra. The Singapore male
agrees well with a male from Java.

The forms with white, instead of fulvous, ground-
colour in the hind wing should be known as form inter-
media Moore. They occur together with the typical fulvous
hind-winged form in Tonkin, Saigon, Siara and the Malay
Peninsula, and therefore cannot be regarded as a separate
subspecies. Distant ^ recognized this in 1886, but
Fruhslorfer ^ records intermedia as a " geographical rac ' "
confined to the Malay Peninsula and Singapore (where he
states it is the principal form) and as an " aberration "
occurring in the dry season in Siam, Saigon and Tonkin.

It seems to me preferable to reserve subspecific names
for geographical races inhabiting separate areas. In this
case two well-marked forms occur together over a wide
range of country. To recognize them by form names
rather than as distinct subspecies appears to me the sounder
policy. If one were a resident form and the other a visitor,
as occurs in some species of birds, {e.g. the Eastern Roller,
Eurijstomus orientalis Linn., which has the typical form
orienlalis resident in Malaysia, and a migi*atory subspecies
calonijx, which is also found at certain times of the year in
Malaysia together witli orientali.s), subspecific distinction
would be justified. There is, however, no evidence to sho\i'
that either form of plea'ippus is an occasional visitor to our
subregion. It is to be supposed in fad that tbe two forms
will occur in one brood. A breeding experiment to test
this would be of interest. On the other hand it might be
argued with some justice that individuals which produce
dimorphic broods in one area are subspecifically distinct
from individuals in another area where only one pattern
of progeny is produced, not two.

One male in the F.M.S. Museums from Kuala Kangsar
has a very slight development of white in the discal region
of the hind M'ing above and is thus intermediate between
the typical forni with completely fulvous hind wing and
the white hind winged form intermedia. This form may
be termed connectens f . nov.

Of 60 specimens in the F.M.S. Museums, 43 are males,
17 females. In tlie Raffles Museum there are 11 males and
3 females. Apparently on the wing all the year round.

Tliere is a melanistic tendency noticeable in the hind
wings of certain males which have the white post-ceUular
streaks, especially those immediately above the scent-patch,
much reduced. These are typical hegesippus, but there are
several examples in the above series which agree admirably
with Fruhstorfer's figure of D. m. indicus.' This form he
lestricts to Tenasserim, Burma, Bengal and Cochin-China.
(iodfrey - regards the Siamese form as hegesippus. The
three he sends me are typical hegesippus, differing particu-
larly from Fruhstorfer's figure of indicus in the reduced
sub-apical white markings of the fore wing. I doubt
whether the Indian form can be maintained as a separate
subspecies.

24a. Danaida melanippus Cr. insulan's subsp. nov

Differs from .lavan mehinippus in the hind wing,
which is noticeable for its white cell, contrasting with three
pale ferruginous streaks bordering the submedian and
internal neivurcs. The post-cellular streaks are white and
much reduced, but shaded posteriorly with ferruginous
scales ; the white spots of the hind-marginal border are
reduced. The whole of the discal region of the hind wing
below is pale ferruginous, not white as in hegesippus.

This Krakatau form suggests a possible hybrid between
hegesippus and melanippm. Possibly stragglers of
melanippiis from Java and hegesippus from Sumatra have
reached Krakatau since the great eruption and have given
rise to this new race.

From the Engano form pietersi' it is easily distin-
guished. That form has a brown cell centre and brown
inter-nervular streaks on the hind wing ; there is also a
powdering of grej-violet on the white sub-apical patches
of the fore wing which is absent in insularis.

Fruhstorfer (I.e.) states that for a decade only one
male was known " whose locality, the Malay Peninsula,
was moreover still doubtful." The record of a male from
Johore and two more from Kuala Selangor is therefore of
interest. Distant {I.e.) records its discovery in Province
Wellesley. The Kuala Selangor males agree well with
Fruhstorfer's figure and with Siamese males kindly sent to
me for comparison by Godfrey. Distant's figure of the
Province Wellesley female agrees with Siamese females,
except that the white discal region of the hind wing is not
so sharply defined in his figure.

The Johore male in the Raffles Museum differs so much
from malayana that one is tempted to give this southern
lorm siibspeciiic distinction. I jjrefer, however, to keep
it provisionally under malayana until the female and more
males are collected. The white discal region of the hind
wing is much restricted as in Fruhstorfer's figure of tam-
hora (fig. 77d.), the outer half is brown, with the veins

a double hind-marginal border to the hind wing are smallei

upper side.

Fruhstorfer states that malayana is fairly numerous
in Bangkok, and that it will, in his opinion, certainly extend
still further along the coast of Siam.

Fruhstorfer comments on the rarity of this form.
The Director of the Zoological Museum, Buitenzorg, has
sent me for examination three males and one female from
Purmerend and Edam, Batavia Bay. They agree weU with
Piepers' figure ^ ; they measure 55-65 mm. across the wings
against 50 mm. recorded by Fruhstorfer. Piepers^ states
it is common in the low^er districts of Batavia.

The subgenus Danciida contains one other species from
the Malaysian subregion in addition to the above.

The following key, which is based on male characters
only and therefore does not apply to females, will serve to
distinguish the ditterent subgenera, or " groups " as
Fruhstorfer regards them, into w^hich this genus is
divided : —

a. Without pale patch of specialized scales
in the costal rei'ion of hind wing.
b. Without sexual brand on fore wing Menama.

l)\ With one well-detined sexual brand be-
tween median and internal nervures of
fore wing Crastia.

b\ With two well-defined sexual brands be-
tween median and internal nervures of
fore wing Stictoploea.

a\ With pale patch of specialized scales in
the costal region of the hind wing of
the male.
b. Patch quite small, in cell of hind wing
below the origin of first subcostal
nervule Trepsichrois.

Subgenus Menama, Moore.

Fruhstorf er ^ merges this subgenus under the one
group Crastia. Tlie absence of any sexual brand in the
male, however, seems to justify subgeneric separation of
the three species thus characterized from those in which
there are one or more well-defined sexual brands. I there-
fore follow Bingham^ in retainmg this subgenus distinct
from the subgenus Cra.slia. De Niccville^ follows Butler*
in using Hubner's name Crastia for the species here placed
under the subgenus Menama, i.e. those characterized by
the absence of a sexual brand in the male.

The remaining species included by Fruhstorfer in his
group Crastia, and by Butler and de Niceville in their
groups Eiiploea, Bingham refers to his subgenus Crastia ;
a course which I adopt here.

The species of Menama found in the Malay Peninsula
may be distinguished as follows : —

a. Colouring above black fuscous without purple
iridescence ; hind-margin fore wing with
white spots, hind-margin hind wing with
double row of small while spots.

b. Sub-apical spots in fore wing large. Exp.

al. 88-98 mm. Apex fore wing roundea marsdeni.
b\ Sub-apical spots in fore wing not large,

very slightly more pronounced than inner

row of post-discal white spots. Exp. al.

110-118 mm. malayica.

a\ Fore wing deep iridescent blue-purple on
black, without spots in male and only a
few small sjiots in female, hind wing both
sexes marked with double row of sub-
marginal spots, those of the inner row
elongate and heavier modesia.

Distrib. The type form crameri comes from Borneo.

The species is reduced to several subspecies ranging from
India through Malaysia as far East as Bali. The Malaysian
subspecies are : —

E. c. crameri Luc. Borneo.

E. c. marsdeni Moore Malay Peninsula.

E. c. heylaertsi Moore Sumatra.

E. c. niasica Moore Mas I.

E. c. mentavica Hag. Mentawei Is.

E. c. pagciistecheri Hag. Bawean I.

E. c. singaradha Fruhst. Bali.

E. c. lanista Fruhst Xatuna Is.

E. c. jedja Fruhst. Banguey I.

The Tenasserim subspecies bremeri and the Sumatran
heylaertsi appear to me hardly separable from the Malay
Peninsula marsdeni.

The two males from Langkawi Islands do not differ
from the mainland form. The only male from Tioman
Island on the other hand is noticeable for the almost total
suppression of the hind-marginal border of white spots in
both wings. If this reduction is normal in males from that
island, subspecific separation would certainly be justified.
The two females from Tioman, however, do not differ from
mainland females.

27a. Euploea crameri Luc. sncUeiu' suhsp. nov.

Snellen ^ notes that the typical form crameri of Borneo
*' differs from the Javanese form in being larger (80-82
mm. against 70-77 mm.) and in being of a somewhat
darker colour. The white spots on the fore wings, more-
over, are almost limited to the apex, being also larger."

As Piepers points out, these notes do not agree with
Fruhstorfer's description of tenggerensis, which we may
regard as restricted to the Tengger Mts. in East Java. For
the ordinary Javanese form of crameri, which is thus
without a name, I propose the name snelleni. Piep^irs (I.e.)
figures both sexes.

Loc. Singapore (Raffles Mus.). Province Wellesley

Fruhstorfer restricts core to India, with subspecies
in the Himalayas, Ceylon and the above for the Malay
Peninsula. Moore ^ gives no more definite locality for his
type of graminifera. Fruhstorfer {I.e.) states it is un-
known to him in nature.

Moore describes distanti from Sumatra and gives, as
an additional locality, the Malay Peninsula (Province
Wellesley) . Fruhstorfer suggests that distanti is the repre-
sentative of core on Sumatra, but he retains the two as
separate species. The single Singapore male in the Raffles
Museum agrees well with Moore's figure of distanti,' which
in turn is very close to the Sumatran form. I think there-

' Moore, 1883, pp. 277-278, pi. XXIX, fig. 6. ~

fore that it is preferable to regard both graminifera and
distanti as subspecies of the continental core. The
Malaysian subregion thus has : —

E. c. graminifera Moore Malay Peninsula.

E. c. distanti Moore Sumatra.

Swinhoe's circuita from Tonkin, Cochin-China and

A series of 16 in the F.M.S. Mus. from Pulau Condore
(Lat. 9° N.) off the S.E. coast of Cochin-China is referable
to this form, which Fruhstorfer and Godfrey unite with
the preceding species H. godarti.

I agree with Bingham in keeping them separate, as
this series difl'ers imiformly from godarti in the sexual
brand on the fore wing of the male. This is broader and
double the length of that in godarii. It further differs in
the absence of a lilaceous patch in the apex of the fore wing
so prominent in godarti, and in the straighter inner row
of submarginal spots in the hind wing.

Godfrey states tiiat godarti is very common in Siam,
but that the form tai/ardi is not. Breeding experiments
to prove the conspecific identity of the two forms are
needed.

I regard this with some doubt as a mountain form of
alcathoe, since there are three other specimens in the F.M.S.
Museums (1,J, 2$ $) of the typical gardinevi form from
the same locality. It is possible that these were taken at
the foot of the mountain and that monticola is restricted
to the higher altitudes. The appearance of monticola
however is in some ways so strikingly dift'ercnt from
gardineri that it may perhaps turn out to be a distinct
species.

Fruhstorfer {I.e.) keeps as separate species : harrisi

and dufresne for the Philippine Islands. It seems to me
preferable to treat them as one species, subspecrfically
distinct from one another in their own particular regions.
I therefore adopt the oldest name dufresne Godt. for the
species instead of harrisi. Fruhstorfer evidently inclines
to the same view, as he writes : " Whether all the three
species now regarded as separate belong to one species is
a question which can only be solved by further anatomical
research." hi discussing Austro-Malayan forms' hv writes:
" But in spite of all the statements to the contrary, there is

female in Godfrey's collection) has but one small violet
dot in the apex of the cell of the hind wing and on the
underside only. A Singapore male is the same in this
respect, while another has this violet dot on the upperside
but not on the underside. The sub-apical spots of the
fore wing are rather smaller in drucei than in phoebus.

Subgenus Salpinx, Hiibn.

This subgenus is characterized by a patch of light

Distrib. E. leucostictos ranges from India to For-
mosa, south and east through Malaysia to the Mariannes.
The subspecies occurring in the Malaysian subregion are : —

E. I. leucogonys Butl. Malay Peninsula (Siam and

Burma).

E. I. vestigiata Butl. Sumatra.

females. Both -sexes are very variable both in markings
and size. In the Raflles Museum series oi 25 males from
Bukit Kutu, all taken in xVpril 1915, the expanse of wings
varies from 68 to 100 mm.

Although this species is at once distinguished from the
next, midamns, by the presence .of apical v^hite spots in the
fore wing, nevertheless, as Fruhstorfer points out, its
relationship to that species must be very close.

Apparently aegyptiis represents a group of island form§
extending as far north as Singapore, but not occurring on
the Malay Peninsula i)roper, while midamiis is a continental
species, with a geographical race known as E. m. dejeani
extending down the Malay Peninsula as far south as Negri
Sembilan, but not so far as Singapore.

DistriJb. E. m. dejeani is the only form occurring in

the Malaysian siibrogion. OHior subspecies occur in Siam,
Assam, Nepal and South China.

The F.M.S. Museums series of 8 males and 1 female
shows an interesting gradation from the Siamese form with
blue gloss on the fore wings and reduced white sub-
marginal spots in the hind wing to another from Kedah, still
with the blue gloss but with larger white sub-marginal spots
in the hind wing, merging finally into examples from fur-
ther south in which the blue gloss practically disappears
altogether.

A male in the Ratllcs Museum from Pahang goes one
step further in showing distinct traces of wliite apical spots
in the fore wing, thus approximating the last form discussed

190 Journal of the F.M.S. Museums. I Vol. X,

{E. a. singapura), which appears to l)e confined to Singa-
pore. This Pahang male, however, and a female bearing
the same localitj' label approximate the Siamese form in
having the hind-marginal spots on the hind wing much
reduced. It is evidently a variable species and it would
probably be more correct to make the aegyptus group of
forms subspecies of midamus. Distant's description and
figure of E. chloe from Province Wellesley, Malacca and
Singapore, suggest connecting links between the two. His
figure of margarita shows pale blue spots on fore wing
which I have not seen in Malay Peninsula examples of this
species.

Loc. Kedah (Distant).

Distant's single specimen from Kedah appears to be
the only record of the species in the Malaysian subregion.
The typical form occurs in Siam and Indo-China, with sub-
species in India and Ceylon. The elongated pale violet
apical spots in the fore wing, practically connected with
well-defined whitish spots on the apical half of the hind-
margin, render this species easy to distinguish from the
other species of this subgenus.

A common butterfly throughout the Malay Peninsula.

In a series of 78 males out of 80 specimens from the
F.M.S. Museums the only variation to be noticed is in the
small white post-cellular spot of the fore wing upper side.
This varies in size ; is absent altogether in one from Kelan-
tan ; in others it is well-formed and triangular in shape,
while in a few there is a second spot below it.

E. diocletianus is typically a Malaysian butterfly, with
the following subspecies recognized in our subregion : —

/•r. d. diocletianus Fab. Malay Peninsula, Sumatra

(and Siam to Burma and
Assam).

E. d. lowi Butl. Borneo.

E. d. aerithus Fruhst. Natuna Is.

E. d. alcidice Godt. Java.

E. d. schildi Fruhst. Batu Is,

One other subspecies occurs in Northern India,

VI. THE APPLE-SNAILS OF THE MALAY PENINSULA.

By N. Annandale, d.sc, f.a.s.b.
Director, Zoological Siirvcif of India.

Mr. Bodcn Kloss has been kind enough to send me for
examination the shells of Ampullariidae in the collection of
the Federated Malay States Museums and has asked me to
give him some nolcs upon them for publication. This
I gladly do, if onlv to call attention to our ignorance of the
freshwater molluscs of the Malay Peninsula. De Morgan^
and Moellendorf- have pubhshed lists and descriptions of
the Perak species, NevilP has described and annotated a
few Ampullariidae and Viviparidae from Penang and Perak
and I have done so for a few species and races of the former
family* from the Siamese Peninsular Provinces ; but the
whole of malacological literature nuist be searched for a
few scattered references to the species that occur in the
southern parts of the Peninsula.

The collection of Malayan Ampullariidae I have
examined is not a large one, but it includes specimens of
all the species described from the Peninsula and the Archi-
pelago. The type-specimens of three Peninsular forms are
also in my hands, namely Pachi/labra stoliczkana (Nevill)
P. lurbinis siihampullacra (Nevill) and P. tnrhinis laciis-
tris, Annandale. These specimens belong to the collection
of the Zoological Survey of India and are preserved in the
Indian Museinn.

The following forms are known from the Siamese
Peninsular Provinces, Penang, " Malacca " and the Feder-
ated Malay States ; possibly otliers may occur in Singapore,
Johore and other southern districts, but none, so far as I
know, have been lecorded.^

Two specimens in tlie collection received from the
Malay States agree closely with the types of Stoliczka's
species, which are in the Indian Museum. They also seem
to me to agree sutiiciently closely with de Morgan's figures
of his A. welleslijensis from the same locality, allowing for
the fact that the figures are based on a specimen m which
the apical part of the spire had been completely destroyed.
Further they have a close resemblance in outline to two of
Kobelt's figures of P. turbinoides, namely those cited above,
one specimen resembling each figure.

As Stoliczka's original description is difficult ol access
I quote it in extenso : —

" Though I very much doubt if the Penang form can
be really distinct from the many described species, still I
find it impossible to class it even as a variety of any of
the species I know. Its substance, shape of the whorls,
etc., distinguish it at a glance from all the forms I have
grouped together as A. conica. It a good deal resembles
Reeve's fig. 37 A. turbinoides (Australia) ; it is, however,
more oblong, ovate and contracted in shape, with sombre-
brown, polished coloration. In these latter respects it
closely resembles A. polita from which its shape and
produced spire easily distinguish it. A. callistomo, Mori.
(Ser. Conch., Livr. IV, Pt. 13, fig. 7 ; Cambodia), is still
closer, though indeed this seems to me to be scarcely more
than a small variety of A. polita. Reeve's fig. 96 of his
A. javanica (Java) may perhaps prove to belong to one
and the same species ; the typical figure is apparently taken
from an immature shell, and it is therefore impossible to
decide without actual comparison.

Ovately oblong, with six regularly produced whorls, the
last not swollen (or subangulate) above as in A. polita and
A. callistoma ; scarcely imibilicate ; aperture contracted
and produced, marked interiorly with faint interrupted
bands, slightly effused at base ; epidermis polished, brown.

(7) Penang ; coll. Stoliczka. Three lull-grown and

1921] Annandale : Apple-Snails of the Penin.sitla. 195

Stoliczka's type-series was from Penang, while de
Morgan gives the same island and Lariit, Perak, as localities
for his A. welleslijen.si.s. The new specimens are from
Selangor.

I think that Nevill was right in treating this form as
a variety of P. conica. as some individuals might be
assigned either to it or to the forma tijpica of that species
with almost equal justice. Only tiie specimens from Bhamo
ill Nevill's collection can, hoAvevcr, be assigned to it, those
from Tenasserim representing P. gracilis.

The variety was described from " Malacca." According
to Kobelt it occurs in Assam as well as in Upper Burma.
The forma ti/pica of P. conica is widely distributed in
Burma and has been found in Northern Siam.

Pachylabra gracilis (Lea).

1!I2(I. Pachylabra gracilis. Aiinandalp, Journ. Nat. Hist. Soc. Siam, IV (1920),
p 11, pi. i, ng. 4.

The differences between this species and P.
conica noted in the paper cited appear to be constant in
the fairly large scries now^ before me. The internal
colouration of tiie shell also is characteristic (iig. cit.).
The largest shell I have seen is 37 mm. high and 31.5 mm.
in maximum diameter.. The apex is eroded and the shell
has the appearance of being adidt.

There are specimens in the F.M.S. Museums collection
from Penang and the Kinta district, Perak. The
species has hitherto been known only from northern Siam,
but the shells from Tenasserim labelled A. conica var.
compacla by Nevill certainly belong to it.

Pachylabra perakensis (de Morgan).

ISS.'). Anipiillaria perakensis, do Morgan, op. cit., p. 418, pi. viil, fig. 12.

The colouration of the shell is evidently variable. Dc
Moi'gan describes it as, " Caerulea, multis croceis faciis
ornata," but in the specimens I have examined it is of a
bright yellowish olivaceous shade with a few faint darker
spiral bands. The shape, high polish of the surface and
sculpture of very tine longitudinal costae are, howevei',
characteristic.

De Morgan records the species from the lower Kinta
aii<l Plus valleys. There are specimens in the Kuala Lumpur
collection from Perak and Selangor and Mr. Boden Kloss
recently- sent me one from Benong on the Isthmus of Kra
on the Siamese side of the Pakchan river.

This form, which I have discussed at length in the

Ihe Malay States as well as of the Siamese Peninsular
province of Singgora. De Morgan records it from Penang
and Rhaman as well as from both the upper and the lower
Kinta and Plus valleys in Perak. It is not known to range
north of the Tale Sap or Inland ?>ea of Singgora. Several
authors have confused it wdth P. ampiillacea (Linn.)

VII. TWO NEW BATRACHIANS AND A NEW SNAKE

FROM BORNEO AND THE MALAY PENINSULA.

By Malcolm A. Smith, F.Z.S.

(Plate n.)

I am indebted to the Director of the Federated Malay
States Museums, for the opportunity of examining two
separate collections of reptiles and hatrachians. One of
them was made by the native Museum collectors in 1919,
upon Mt. Dulil, Sarawak, Borneo ; the other, also in the
same year, during the expedition of Messrs. Robinson and
Kloss to Peninsular Siam. Amongst a large amount
of interesting material tlie following species appear to be
new : —

Rana pullus, sp. nov. (pi. 11, fig. 1).

Vomerine teeth in two very oblique series, commencing
between the choanae and extending well behind, the distance
between them less than their distance from the choanae ;
tongue without median papilla ; head as long as broad,
snout rounded or obtusely pointed, feebly projecting beyond
the mouth, a little longer than the eye ; canthus rostralis
(jbtuse, loreal region obli(|ue, concave ; nostril nearer the
tip of the snout than the e>e ; distance between the nostrils
e((ual to or greater than thai of the upper eyelid ; tympanum
very distinct, 1/2 to W/Tt the diameter of the eye.

Fingers moderately long, first slightly shorter than
second ; tips with moderately large discs, which are a little
broader than long, and with a groove in front separating
the upper from the lower surface ; subarticular tubercles
large and prominent ; discs of the toes like those of the
fingers ; toes half webbed, the web reaching the disc of the
fifth toe and penetrating to a ([uarter between the outer
metatarsals ; subarticular tubercles moderately prominent ;
a tarsal fold ; inner metatarsal tubercle feebly prominent,
'^/A to 4/5 the length of (he inner toe ; no outer tubercle ;
tibia 2 to 2V4 times in (hslance from snout to vent, as long
as or a little longer than Ihe fool ; the heels meet when the
limbs are folded at right angles to the body ; the tibiotarsal
articulation reaches the snout or not quite so far.

Skin witli a glandular network of fine folds, the reticu-
lations largest and best marked al)ove.* A strong glandular
fold irom the eye to the shoulder.

Dark grey or blackish above, whitish below, thickly
speckled, except on the belly, with, dark grey. Some of the
young have light and dark bars on tlie hind limbs.

* The skin of tliis frog is unusually tender. There is not a
single example in the serius in which the skin is not torn or
damaged in some part of Ihe hody. The glandular reticulations
leferred to are possibly not so prominent in life as in spirit
specimens.

Journal of the F.M.S Museums [Vol. X,

This frog does not appear to have any very clbse ally.
Mr. Boulenger, who kindly examined the series with me,
placed it near to Rana heddomii (ninther, from Southern
India.

Males smaller than females, without vocal sacs, and
with an enlarged (pale) pad on the first finger.

Eggs large and few, unpigmented, the vitelline sphere
measuring 2 mm. in diameter.

Nasals largely in contact with each other ; terminal
l)lialanges Y-shaped.

Type series in the British Museum. Type locality,
Tasan, 25 miles S.W. of Chumporn, Peninsular Siam.

46 specimens examined, all from the type loca)ity, with
one exception from Mamoh, in Renong (No. 4501 ) .

VIII. SOME WATER-SNAKES NEW TO, OR RARE
IN, THE MALAY PENINSULA.

By C. Boden Kloss, i .z.s.

The following rare water-snake of the sub-family
Homalopsinae is new to the fauna of the Malay Peninsula :
it was obtained by a native collector at the mouth of the
Kurau River at the northern extremity of the coast of Perak
in January 1917.

1. Gerardia prevostiana.

Coluber {Homalopsis) prevostiimiis Eyd. & Gerv. in
Guer. Mag. Zool. cl. Ill, 1837, p. 5, pi. XV.

Gerardia prevostiana Boulcnger, Fauna Brit. India,
Rept. p. 379 (1890), id.. Cat. Snakes Brit. Mus. Ill, p. 20
(1896).

The single specimen obtained agrees with Boulenger's
descriptions {l.c.s.) except that the temporals are 2 -f 2
and there ai'e three i)raetrontals, the median one being
smaller than the others and broadest in front.

Snout to vent 305 mm., tail 45 mm.

Hitherto apparantly only known from Burma, India
and Ceylon.

2. Fordonia leucobalia.

Homalopsia leucobalia Schleg. Phys. Serp. II, 1837,
p. 345, pi. XIII, figs. 8, 9.

Fordonia leucobalia Boulenger, Vert. Fauna Malay
Pen., Rept. & Batr. 1912, p. 164.

The collector secured on the same occasion one example
of the variety named F. unicoloi by Gray. Snout to vent
350 mm. ; tail 50 mm.

This species ranges from Bengal to Cochin-China and
North Australia. It has been taken at Singapore and at
Penang, where Cantor says it is common, but the present
specimen is the first we have met with.

3. Herpeton tentaculatum.

First recorded from the Malay Peninsula by Dr.
N. Annandale (l.c.s.) who obtained it in the Tale Sap or
Inland Sea, Singgora.

202 Journal of the F.M.S. Mii.seiims. [Vol. ,X,

This curious snake is easily identified by means of the
rostral appendages which occur on either side of the snout :
for an account of these see Smilli. Journ. Nat. Hist. Soc.
Siam, I, 1914, p. 109 and plate.

To include these the " Synopsis of the Genera " in
Mr. Bouleni^er's volume of Reptilia and Batraclia of the
Vertebrate Fauna of the Malay Peninsula (p. 158) may be
altered as follows : —

No tentacles on the upper lip

fX. NINE NEW ORIENTAL BIRDS.

By H. C. Hoijinson and C. Bodkn Kloss.

1. Treron bisincta praetermissa subsp. nov.

Larger than T. h. bisincta (Jerdon) from Madras
(wing 144) : ditlers from T. h. donwilii (Swinh.) from
Hainan in having the grey nuchal patch in the female clear
and more extensive whereas, fide Hartert, it is indistinct and
small in the island bird (Nov. Zool. XVII, 1910, p. 193).

Hartert has inadvertently described the Ceylon birds
as being smaller than Madras individuals (l.c.s.) though
his specimens are exactly the vsame size as typical birds,
and leygei is therefore synonomous with h. bisincta.
Svvinhoe states that domvitii is smaller than the typical
form (presumably the bird now descrilx^d), but this is
denied by Hartert.

The range of this race is probably from Bengal and
Assam southward to the Malay States, and in the north,
eastwards to China where the wing averages 156 mm.
(fide Baker, India Pigeons and Doves (1913) p. 51).

Tiipes. Adult male and female from Koh Lak, South-
West Siam. Collected bv H. C. Robinson and C, Boden
Kloss on 5th April, 1919. * Collector's Nos. 5075, 5074.

Wings 162, 161 mm.

Specimens examined. Thirteen from the Malay
Peninsula. Wings 157-163 mm.

Birds from East and South-Kast Siam and Java
(apparently first met with in the island by Ivloss early in
1920) are smaller, the wing being always under 150 mm.
and these may represent another race. We expect to settle
I he point shortly.

2. Macropygia emiliana borneensis, subsp. nov.

Differs from the typical race from Java (typical locality
here specified as the plains of Central Java) in having the
head and nape distinctly darker, the breast more amythsline,
the centre of the abdomen paler, tending towards buff.
Wing of type, 163 mm.

Type. Adult nuile collected at Lingit, Saribas,
Sarawak, Western Borneo, bv Native Collector in March,
1917.

Scries examined. Five adult males and two females,
ail from Sarawak, compared with a large series of Javan
birds liom all parts of the island. Si)eciniens from Java,
attain a greater length of wing than any of our Bornean
birds (one male, 1(S0 mm.).

.'{. Zanclostomus javanicus pallidus subsp. nov.

Differs from Z. j. javanicus (Horsf.) of Java as being
paler below : the rufous area less iulense and (he p,vo\ \yA\ov
and more washed with but!',

204 Journal of the F.M.S Museums. [Vol. X,

Type. Adult male from Kedali Peak, Malay Peninsula,
2,500-3,500 ft. Collected by H. C. Robinson and C. Boden
Kloss, 4th December, 1915.

Twelve specimens from Bandon to Negri Sembilan
compared with fourteen from various parts of Java. A
Sumatran and a Bornean example do not apj)ear to difi'ei-
irom Malayan birds.

We believe that all the names which have been referred
to tliis species api)ly to the Javanese form : javanicus, of
course ; but also Coccyzus rnhiirostris Drap., Piaya
evylhrorbyncha Less, and P. chrysogaster Less. P.
crythioi'hyncha was stated to come from Java and, if so,
the description will only tit this bird : P. chrysogaster
seems to be the same thing though recorded as from Guiana
and we attach the name to tiie Javan form rather than
to the other as the forehead is stated to be rustv yellow,
the breast slate coloured and the abdominal region, etc.,
chocolate red. As a matter of fact the forehead of puHinicus
is not red ; but that colour extends upwards in front of the
eyes to a much greater extent than in the race now described.

4. Brachylophus puniceus continentis subsp. nov

The typical race of this woodpecker from Java B. p.
punier as (Hoisf.) is very distinct, the earco verts being
darker green and the back and rump entirely lacking any
tinge or tleckings of golden yellow.

Hartert (Nov. Zool. Ill, 1896, p. 542) separated the
birds of the Malay Peninsula, Borneo and Sumatra (type-
locality) on these grounds and named them Gecinus
puniceus ohservandus.

Seven Sumatran birds befoi-e ms (wing 115 123) are
distinctly smaller than our series fro)>i the Peninsula. For
the present we content ourselves with naming the Malayan
I'ace as above.

Larger than B. p. oJjservandus from Sumatra. Wing
of t^pc 132 mm.

Type. Adult male collected at Tapli, Pakchan Estuary,
Renong, North Malay Peninsula by H. C. Robinson and
C. Boden Kloss on 3rd March 1919. Collector's No. 4382.

Specimens examined. Seventeen from Chumporn to
Negri Sembilan. Wings 123-136 mm.

Six Bornean birds have the wings 118-126 mm. and
seem to average about the same size as the Sumatran form
with which we leave them.

5. Eupetes macrocerus borneensis subsp. nov.

Like E. m. macrocerus Temm. of Padang, Sumatra,
and of the Malay Peninsula (E. m. griseiventris Baker)
but rather more deeply and richly coloured.

Compared with a topotype from West Sumatra and
six adults from the Malay Peninsula,

Type. Adult male from Samarahan, South Sarawak,
obtained on 25th. November 1910 by F.M.S. Museums'
Collector.

Specimens examined. The type, five from the Baram
district and one from Penrisen, Sarawak, Borneo.

Measurements of the type : length, 270 ; wing 93 ; tail
122 ; tarsus 41 ; bill from gai)e 33 mm.

6. Drymocataphus tickelli australis, subsp. nov.

Southern birds from Bandon to the southern limit of
the species in Selangor, where it is strictly a montane bird,
are decidedly richer coloured both above and below than
typical ones.

Types. Adult male and female from Ginting Bidei,
Selangor 2,300 ft.. 5th and 16th April, 1917, collected by
C Boden KIoss.

" Iris crimson, maxilla brown, mandible yellowish
lleshy, feet fleshy."

Wing 5 66 : $ 64 mm.

Specimens examined. Twenty-seven from Bandon,
Trang, Perak and Seiangor.

7. Malacocincla sepiaria barussana, subsp. nov.

Type. Adult female, Siolak Dras, Korinchi, West
Sumatra, 3,000 ft., collected on 18th March, 1914, by H. C
Robinson and C Bo<len Kloss.

Ditlcrs from the .lavan forms of M. sepiaria in darker
coloLuation ; l)ack reddish iiisset, tail more rufous chestimt,
foreneck greyer, breast and al)domen darker sutt'used with
russet : white centre to the abdomen reduced. Crown dark
as in M. s. minor (Meyer) of E. Java.

From the Malayan form M. o. tardinata, Hartert, it
diflers in having a distinctly dark cap and deeper colour
throughout.

Specimens cvamined. Fourteen from various locali-
ties in West Sumatra, coiupared with seven from East and
Mid-Java and thirteen from the Malay Peninsula.

8. Horizillas rufifrons indochinensis, subsj). nov.

rather less brightly rufous, the lowest upper tailcoverts
distinctly less so. Size ap[)arently rather smaller (15
Javanese birds, wings ()9 81 : 2(1 Indochinese, 67-75 mm.).

Types. Adult male and female from Trangbom,
Cochin China, collected on Jth June and 31st May by C,

Setaria rufifrons was described by Cabanis as from
Sumatra or Java. Biittlkofer has deliberately attached
lepidocephala. Gray, to Javanese birds and they will have
to bear that name if different from Sumatran examples :
but Sharpe, after inspecting specimens in Lej'den stated
that the differences lie noted in the " Catalogue " did not
exist.

As several Javanese birds have wings of 79 to 81 mm.
Finsch's statement that the wing of the type of rufifrons
measures 80 mm. (3 inches of Cabanis) is confirmed.

This is one of the species which, though occurring in
Indo-China and the Sunda Islands, is not found in the
Malay Peninsula.

and Setaria Blyth : vide, Smithsonian Miscellaneous
Collections, 48, 1905, p. 64).

9. Prionochilus maculatus septentrionalis subsp. nov.

Male. Differs from the form inhabiting the southern
part of the Malay Peninsula (20 specimens from the Malay
States compared) in having the ear-coverts much greyer,
hardly if at all waslied with green ; the white throat stripe
narrower and the yello\N of the underparts considerably
brighter, becoming almost orange chrome on the middlit'
of the breast.

Female. Differs in a similar manner from the female
of the southern race.

Iris red or reddish ; maxilla black, mandible slate, the
tip sometimes black ; feet dark slate or slaty black.

X. NEW AND KNOWN ORIENTAL BIRDS.

By C. Boden Kloss, m.b.o.u., c.f.a.o.u.

ON THE PROPER NAME OF THE BLACK DRONGO WITH
DESCRIPTIONS OF TWO NEW SUBSPECIES.

The name by which the Black Drongo has hitherto been
lviio\vii specifically, Dicriirus atra (Miiscicapa atra
Hermann, Obs. Zool. 1804, p. 208 : Tranquebaria, S. India)
is preoccupied by Muscicapa atra GmeUn (Syst. Nat. ed. 13,
1, 1788, p. 946) and Dicrurus macrocerciis Vieillot, must
replace it.

All the following are based on " Le Droiigolon " of
Levaillant (Ois. d'Afr., iii, 1802, pi. 174) so all belong to
the same bird : but macrocerciis has priority : —

Dicrurus macrocercus Vieillot, 1817

Muscicapa biloba Lichtenstein, 1823 " Ind. Orient "

Dicrurus indiciis Stephens, 1826 " India "

Dicrurus longus Bonaparte, 1852 " Java "

Levaillant, however, recorded no locality for " Le
Drongolon," nor did Vieillot for macrocercus ; and we have,
therefore, to look for a " terra lypica " among the others.

The " Ind. Orient " of Lichtenstein is too vague to
supply the need as it merely means the East Indies of Asia
as distinguished from the West Indies of America and there
are several races of Black Drongo.

But Stephens' Dicrurus indicus, " India " is quite
definite and must therefore be accepted as the typical
locality for " Le Drongolon ' and, therefore, for the first
Linncan name, macrocercus, applied to it which, by the
subsequent description of the northern Indian form as
albirictus by Hodgson in 18»<7, becomes by elimination the
name of the Peninsular Indian subspecies.

Bonaparte's citation of Bengal for macrocercus
(Consp. Av, I, 1850, p. 351) confirms this selection and his
attribution of Java to longus (t.c.p. 352) and Walden's of
the same place to macrocercus (Journ. Asiat. Soc. Bengal,
1875, pt. 2, Extra No., p. 129), though he says quite rightly
that both these are the same bird, come too late ; while
the reference of biloba to Java by Gabanis (Mus. Hein I,
1850-1, p. Ill) cannot be accepted.

Thus ai'e ruled out for further use all names based on
" Le Drongolon."

The races of the Black Drongo, Dicrurus macrocercus,
therefore are :—

1. Dicrurus macrocercus macrocercus Vieill. (syn. biloba, iiulicii.' ami longus^,

Dicrurus macroccrcus thai siibsp. nov.

Like 1). in. nuicrocercns of Peninsular India but with
Ihe wing shorter and the wliite rictal spot rarely present
instead of rarely absent (present onee in ten only : whereas
in D. in. macrocerciis it is al^sent once in ten according to
Baker in Nov. Zool. XXV ; 1918, p. 277).

Ditters from D. m. ciithoeca in having a shorter bill
and wing while the median feathers of the tail are always
shorter but the outermost genendly longer.

Specimens examined. Twenty from S. Tenasserim,
S.W. and Central Siam and South Annam. Wing 123 140 :
Tail, outermost feathers, 150 178, median feathers, 100 108;

ON THE RUBY-CHEEK WITH DESCRIPTIONS OF
THREE NEW SUBSPECIES.

Having assembled a large series of Chalcoparia
singalensis from Indo-China and Malaysia I take the oppor-
tunity to review the races occurring on the mainland and
the large islands.

Beginning with the northern specimens of the series
1 recognise the following forms : —

1. Chalcoparia singalensis koratensis Kloss.

Kloss, Ibis 1918, p. 218 (Korat, E. Siam).

Males with the rufous of the foreneck not extending so
far downwards as in other races and terminating abruptly
on the upper breast. Remaining lower parts a markedly
brighter, less greenish yellow.

Females with lower parts brighter than in the typical
race (^. s. singalensis.

1921] BoDEN K1.0SS : New and Known Birds. 209

Specimens examined from North Siam, East Siani
(topotypes), South-East Siam, South Annam (14 ^ , 9 9 ).

2. Chalcoparia singalensis interposita Robinson and Kloss,

subsp, nov.

Males with rufous of foroneck extending over the upper
breast and ending gradually. Remaining lower parts not
so brightly yellow as in C. s. koratensi.s but less greenish
than in C. s. singcdensis.

Females like T. .s. koratensis.

Specimens examined from Bangkok, Siam, south
through the North Malav Peninsula to lat. 6° 30' N. (11 3 ,

Types. Adult male from Takuapa, West Coast Penin-
sular Siam. Collected by H. C. Robinson and C. Boden
Kloss on 18th February, 1919. Adult female from Ban Kok
Klap, Nakon Sri Tamarat. Collected by H. C. Robinson
and E. Seimund on 30th June, 1913,

3. Chalcoparia singalensis singalensis (Gmelin).

M-otucillu singalen.six (iiiu-liii Syst. N;il. I, 1789, p. 'J64 (Malacca :
Obcrholser det.)-

Males with rufous of foreneck and upper breast as in
C. s. interposita but with remaining lower parts a rather
greener yellow.

Females with tlie breast and abdomen distinctly greener
than in koraiensis and interposita.

Specimens e.vamined from Pct-ak to Joliore, South
Malay Peninsula (12 i , 9 9).

4. Chalcoparia singalensis sumatrana lvh)ss, subsp. nov.

Males with the rufous of the foreneck and breast
extending still fmther down towards the abdomen and the
latter more tinged ^^^th green than in C. s. singalensis.

Females rather more greenish below than in C. s.
.•singalensis.

Specimens examined from the Ophu' to Bencoolen
districts. Western Sumatra ; and Deli, North Eastern
Sumatra. (9 c5 , 5 9).

Types. Adult male from Mi. Talamau, 400 metres,
and female from Tanangtalu, 1,000 metres, Ophir district.
Central Sumatra. Collected bv E. Jacobson on 27th April,
1917 and 10th May, 1915. Collector's numbers 891 and
4,553.

5. Chalcoparia singalensis borneana Kloss, subsp. nov.

As in C. s. interposita but rufous of the foreneck and
upper breast rather deeper in both sexes.

Specimens examined from various part o>" Sarawak.
(195, 149).

Types. Adult male from Bukar, Samarahan, Sarawak,
obtamed by F.M.S, Museums collector on 26th October,

210 Journal of the F.M.S, Museums. [Vol. X,

1919 ; and adult female from Kuchiiig, Sarawak, obtained
on 24th May, 1892 (ex Sarawak Museum) .

6. Chalcoparia singalensis phoenicotis (Temminck).

S'eclariniu phoeiticotis Teniiiiiiick, PI. Col. 1824, No. 108, flg. I (cf) ;
No. 388 flg. 2 (?) (Java).

Males as in C. s. singalensis but rufous of the foreneck
and upper breast deeper : abdomens less bright than in
C. s.. borneana.

Females with the rufous of the foreneck much deepei*
than in the females of any other race (as deep as in the
males) ; not extending on to the upper breast and ending
abruptly as in males of (^. s. koratensis ; but still more
restricted. Lower breast and abdomen bright as in
koratensis and interposita.

Specimens examined from Rast. Mid and West Java
(7^,3$).

Chalcoparia singalensis panopsis Oberholser (Smiths,
Misc. Coll. 60, 1912, p. 21) of Nias Id., West Sumatra, is
described as having the females with the posterior lower
parts more brightly yellowish than in C. s. singalensis.
It must, tlierefore, be quite distinct from the adjacent race
C. s. suniatrana.

Of the males C. s. koratensis, of the females C. s.
phoenicotis is the most distinct.

When I stated. Ibis 1918, p. 218, that birds from the
Malay Peninsula, Sumatra and Java were alike my material
was inadequate, consisting from the latter places of one
Sumatran male only and four old mounted males of faded
colours from Java. C. s. phoenicotis is a very distinct
form on account of the characters of the female : C. s.
sumatrana less so ; but sutficiently distinguished to need
separation.

A NEW RACE OF SHAMA FROM JAVA,

Kittacincla malabarica javana subsp. nov.

Sexes alike in colour and paler below than the males of
K. m. tricolor (Vieillot). Typical locality Bantam, W, Java:
Robinson and Kloss det,^) and with white, not rusty thighs r
like the males of K. m. omissa Hartert (Nov. Zool. IX, 1902,
p. 572. Lawang, E. Java) but without the indistinct white
border to the black breast.

Types. Adult male (No. 6277) and female (6112)
collected by C, Boden Kloss, 23rd and 18th February 1920,

' Extract from M.S. " We consider that Vieillot'.s citation of the
locahty of his Tiirdm tricolor (Nouv. Diet. Hist. Nat. XXX, 1818,
p. 291) ""les isles de la nier du sud " is at least as precise as
llartert's subsequent fixation as " India " (Nov. Zool. IX, 1902,
p. 571). Further the description by Scopoli in 1786 (Del Flor.
Faun. Insubr., II, p. 97) of the Malabar bird as Miiscicapu
malabarica should prevent " India " being selected for a typical
locality. We have, therefore, further fixed the typical locality
of Tardus tricolor as Western Java." H. C, Robinson and C. Boden
Kloss.

1921] BoDEN Kloss : New and Known Birds. 211

at Karangbolang, South Coast of Mid-Java (not Karang-
bolang of Noesa Kambangan Id.).

Specimens examined. Three males and one female
from the type locality : compared with two males and one
female from Pandeglang District, N. Bantam ; one male
and one female from Wynkoop's Bay, S.W. Coast of Java ;
and with two males and one female of K. m. omissa from
Badjoelmati, E. Coast of Java.

A second male from Wynkoops Bay is intermediate
between tricolor and javana ; a little lighter beiow than
the first, somew^iat darker than the latter with white thighs
slightly washed with rusty.

exactly like the male in colouration but my specimen is

XL NOTES ON SOME ORIENTAL B?RDS.

By C. Boden Kloss, m.h.o.u., c.f.a.o.u.

HALCYON (SAUROPATIS) CHLORIS.

Either together or separately Mr. H. C. Robinson and
1 have hitherto not seen our way to accept all the races oi'
Malajsian Blue-and-white Kingfishers that Dr. H. C.
Oberholser recognises and proposes (Proc. U. S, Nat. Mus.
55, 1919, pp. 351 395). But now with about 80 specimens
from Bangkok, south through the Malay P^ninsida to
Johore ; 8 from North-east Sumatra ; 16 from Benkoolen,
the Padang districts and Korinchi, West Sumatra (C.
cyanescens Oberh.) ; and 18 from all parts of Java (C
palmeri Oberh.) I have to revise my opinions somewhat.^

I cannot perceive all the differential characters
Oberholser gives in his key and diagnoses : however, in the
large series of continental birds I find a few males — a
distinct minority- — that are a deeper, less greenish, blue than
the others and these make the series as a whole look more
blue ; as stated, there is frequently a pronounced wash of
buff on the flanks which the others lack : the continental
birds are certainly smaller : and so are eight specimens from
the Deli district of North-east Sumatra, which on this
account I should rank with them, though Oberholser says
that F2ast Sumatran birds as far north as Deli are
(tyanescens. The wings of my continental birds range
from 97 'to 106 mm. ; those of the Deli examples from 96
to 104 mm. : and those of the West Sumatra specimens from
104 to 112 mm.

Oberholser considers that bii-ds from the Sunderbunds
to Singapore are all armstrongi (type, a Siamese skin of
Gould's collection), and that birds called luimii by Sharpe
(type, a Selangor bird of Hume's collection) are insepai--
able : but I find, on the contrary, that the great majority
of birds from the Malay Peninsula have the earcoverts morl'
blackish, or of a darker different bhie, than the birds of the
Inner Gulf of Siam which have the earcoverts of the same
blue as the crown though sometimes a trifle darker in tint ;
and on this ground, and because of a deeper huffy wash on
the flanks and of a pronounced black nuchal band in most
of the specimens (obsolete or absent in the Siamese birds)
hiimii may be maintained for birds of the Peninsula, south
of the Isthmus of Kra and for those of North-east Sumatra.
There seems to be no difference in size : the wings of the
24 more Northern birds (armstrongi) range from 98 to
106 mm. ; those of the Peninsular series from^97 to 106 mm.
and those of the Sumatran set of Inimii from 96 to 104 mm.

of Banka Id.) is defined as from Sumatra to Borneo and
the islands along its east coast with all the intervening
islands ; also Bawean and various islets in the Java Sea.
Placed with this race must be a pair from Pulau Mapur,
the easternmost island in the Bhio Archipelago south of
Singapore, (wings 110 mm.).

Apart from colour differences which I cannot find,
S. c. palmeri Oberh. (tom. cit. p. 368 : tvpe from Mt. Salak,
W. Java : supposed to be confined to Java), is said to be
distinguished from cyunescens by a slightly smaller bill :
the measurements given for the exposed culmen^ are : —
cyanescens (75 examples) 41. 5-47.3* -53.5 mm. ; palmeri
(25 specimens) 42.5-45.9 *-50 mm. [i.e., within the range
of cyanescens]. The bills from gape of my West Mid-
Sumatran specimens of cyanescens measure :- 52-56.4*-
()() mm. ; of my Javan birds 55-57.2*-60 mm. : the converse
of Oberholser's findings.

Averages seem to be untrustworthy as they differ
with different series : both series attain similar maxima
and the smaller-billed Sumatran birds may be immature
though they have no appearance of this. I cannot separate
the Javan birds before me from cyanescens : my series of
the former has a wing range of 103-116, and the latter
104-112 mm.

HALCYON (ENTOMOTHERA) COROMANDA.

Dr. Oberholser has also reviewed the races of the
Ruddy Kingfisher, Halcyon (Entomothera) coromanda
(op. cit. 48, 1915, pp. 639-657) and of Malaysian races which
he recognises, we have material of the following : —

1. Halcyon coromanda coromanda (Lath.).

Southern continental birds are all considered to belong
to this subspecies, which occupies Indo-China ajid the Malay
Peninsula, south to Malacca : Rangoon is selected for the
type locality.

Tills is the largest of the Malaysian forms and the palest
both above and below, being not, or comparatively little,
washed with magenta on the breast [and on the upper
surface, especially the head]. The wing length ranges
from 111 to 119 mm. [Nine practically adult specimens
examined by Oberholser, five from India, one from China,
three from the Malay Peninsula].

' I do not like this measurement : the posterior point is not
iixecl as the forward spread of the frontal feathers, it is very
variable. For instance, in two birds which have the same length of
bill from the gape and from the anterior edge of the nostril, there
is a difference of 3 mm. in the length of the exposed culmen. Both
of the lengths mentioned, which are between fixed points, are
preferable.

* Average. .

2. Halcyon coromanda minor (Tcmm. & Sclil.)

This is recognised as inhabiting Borneo with various
coastal islands, and also Singapore. Pontianak is selected
as the typical locality.

It is a darker bird, particularly below and also mucli
more washed with magenta on head and upper parts
generally] : it is also smaller, the w'ings ranging from 99 to
104 mm. I Five adult specimens examined by Oberholser,
three from Borneo, two from Singapore].

We have no examples of West Sumatran birds which
are named by Oberholser coromanda neophora (type
locality, Tapanuli Bay, Western Sumatra, opposite Nias Id.) :
they are characterised as being like c. coromanda, but
smaller ; lower parts darker and breast Jiiore washed with
magenta, wings 100 111 mm. [Five practically adult
specimens examined by Oberholser, two only from Western
Sumatra]. The habitat is given as Sumatra ; and probably
Banka Id. This race appears on the characters given to be
very like minor, but a little larger [and perhaps paler
above] : but Obserholser's material was small in both cases.

It has already been pointed out' that all Sumatran birds
are not neophora ; four examples from Deli in the North-
east of Sumatra being undoul)te<lly c. coromanda, (though
Oberholser regards his only specimen from N. E. Sumatra,
a juvenile female from Aru Bay, a little to the north of
Deli, as neophora) . This is not surprising as birds taken
on Pulau Jarak, the Aroa Islands and the One-fathom Bank
LightJiouse in the Straits of Malacca are c. coromanda and
it is highly improbable that they were resident on any of
these places.

Thus the range of c. coromanda must be extended to
North-east Sumatra.

To the distribution area of minor must be added
Johore, birds from the south of that State being indistin-
guishable from those of Singapore Island adjticent.^

It seems to ine that a difference between Bornean and
Sumatran birds is as yet " not proven " : Dr. Oberholser's
material from each place was very limited and it may be
noted that he was nnable to distinguish between specimens
of Halcyon chloris from those areas.

Mr. Stuart Baker denies the validity of this race, because
he behevcs that birds from Johore have wings as long as
170 mm. : but he has evidently made a bad geographical
error in attributing to the extreme south of tlie Malay
Peninsula, the specimens which he thinks come from Johore
(Query : Jalor in Patani).

has now been found to extend to the islands of the Rio

ill Timor or the Moluccas.

Birds from Sumatra, Malay Peninsula and Borneo
differ from those of Java in having more black on the
throats in males ; while the throats of females are blackish
blue, distinctly darker than the breasts.

Birds from each of these areas have received a name as
follows : —

PHILENTOxMA PYRRHOPTERA (Temm.).

Philentoma saravacense Bartlett, Sarawak Note-book, pt.
IX (1896), p. 80.

Tliis name was given by Barllett to a blue flycatcher
from the neighbourhood of Kuching. I have seen the type,
a male, which belongs to the Sarawak Museum. It is of
exactly the same size as Philentoma pyrrhoptera
[Muscicapa pyrrhoptera Temm., PI. Col. 1823, No. 596, fig.
2 (error ! read 1) Borneo and Sumatra i, but is of the same
blue all over as the foreparts, except on the abdomen where
the blue of the breast gradually changes more or less into
sullied white.

Agreeing with the type are six other specimens for
the moment in my hands : — a male and female (?) from
Sarawak, Iwo males from the Malay States, and Iwo males
from Sumatra. One of the Malayan specimens has the
flanks slightly tinged with russet.

It has been suggested that this bird is the young of
P. uelata, but 1 am sure (his is not so. It belongs to P.
pyrrhoptera, of which, it seems to be an aberration — though
as shown a comparatively common one- and is not a dis-
tinct species. The colour of the young male P. pyrrhoptera
is apparantly that of the adult female but rather paler on
the throat.

Philentoma intermedius Hume, Stray Feathers, IX, 1880,
p. 113.

This name was given to a female from Johore — an
aberration like that named saravacense by Bartlett. As
usual Hinne's description is very full.

Philentoma maxwelli Bartlett Journ. Straits Branch Royal
Asiatic Soc. No. 28, 1895, p. 96.

This name was given also to a Sarawak bird which
is an ordinary male P. pyrrhoptera except for an irregular
chestnut patch on one side of the blue breast — ^an abnor-
mality 1 find in a Malayan example as well. I am indebted
to the authorities of the Sarawak Musemn for lendmg me
the Bornean types of the synonyms. Malaysian birds are
not separable into subspecies.

CRYPTOLOPHA TRIVIRGATA.

Since we commented on Sumatran examples of
Cryptolopha trivirgata (Journ. Fed. Malay States Mus.
VIII, pt. 2, 1918, p. 167), the F.M.S. Museums have obtained
a large series of this bird from .lava and now comparing
with them an equally large Sumatran series, I can detect no
differences : the birds of the Siuida Islands are larger than
other Malaysian birds and are of tlie typical form C. t.
trivirgata (Strickl., type locality, Java)\

'See, however, Nov. Zool. XXVII, 1920, p. 462 where Hartert
States there is no difFerence in wing length. But tlie series on
which my remarks are based is much larger than any other
assembled.

1921] BoDEN Kloss : Notes on Birds. 219

In 1912 Dr. E. Stresemann found that Malayan birds
were smaller than the Sondaic form and named them
Phylloscopus t. pnrvirostvis (Nov. Zool. XIX, p. 322, Mt.
Tahan, 5,200 ft.). He omitted, however, to compare them
with Bornean material, named bv Sharpe C. t. kinahalaense
(Bull. B.O.C. XI, 1901, p. 60).^ Sharpe described this as
having a duller crown stripe, whitish underparts and a less
yellow colour generally.

But when referring his material earlier to Cnjptolopha
trivirgata (Ibis, 1888, p. 202), Sharpe noted that amongst
it, besides specimens as described, were a few examples of
typical appearance : and he surmised that the latter were
young birds. 1 think the reverse is more probably correct
for I have immature specimens from Java and the Peninsula
whicli approximate to his description.

An adult skin (wing 56 mm.) from Gunong Tanabo,
N. Sarawak, does not ditt'er from Malayan birds : one
cannot dogmatise with a single specimen, but if it is typical
of the aduH C. t. kinabaluense then Malayan birds maj^ have
to bear that name with C. t. parviroslns as a synonym.

LALAGE FIMBRIATA.

I have been able to bring together series of Lalage
fimbriata (Temm.) from Java, Malay Peninsula, Sumatra
and Borneo. There is some lack of uniformity in each
series, because immature males are paler than fully adult
males in some races ; but having regard to adult birds only
my conclusions are as follows : —

1. Lalage fimbriata fimbriata (Temm.).

Cehlephyris fimbriata Teiiiminck PI. Col. Nos. 249 (d) and 250 (?).
Java.

Males perhaps a little darker than males from Malacca,
Sumatra and Borneo, but only doubtfully so.

Females distinct : darker below, but less clearly banded
(bars greyer, less black) owing to a general grey suffusion
or clouding except on the throat and under tail-coverts
where the ground colour is white.

The largest form : wings 99-107 mm. (9 5, 4 2).
Confined to Java.

to develop the dark head and back of the Bornean bird.
Wings 94-105 (5 6 0 5 ) .

MALACOCINCLA SEPIARIA.

In the Trans. Linn. Soc. (XIII, 1822, p. 158) Horsfield
described Braclujpteryx sepiaria from Java and in the
Zeitschrift fin- de (iesammte Ornitbologie (I, 1884, p. 21)
Meyer described Turdinus sepiarius var. minor from the
same island. In Notes from the Leyden Museum (XVII,
1895, p. 82) Buttikofer considered that the latter autlior
could rightly do tliis as Horsfield's sepiaria was the paler-
headed bird. This is actually the case.

I recently obtained in .lava, birds which Mr. E. C. Stuart
Baker has kindly compared for me with Horsfield's types
in the British Museum. The latter represent tlie paler-
headed form, so I am now able to definitely state that
Malacocincla sepiaria sepiaria (Horsf.) is the Western and
Malacocincla sepiaria minor (Meyer) the Eastern .Javanese
form.

Though the individuals of Meyer's type series have
wings much smaller than my specimens, or an}^ others on
record from .lava, it is accepted that they do represent a
form of sepiaria.

Wing measurements of my specimens.

3. From Mid Java (Karongbolang on the S. Coast, 40
miles E. of Tjilitjap) ; 72, 68, 76 mm. These are truly
typical of neither form : the first might be placed with
.s'. sepiaria, the others with .v. minor.

Meyer gives wings of 61-64 mm. for minor ; 70-72
mm. for sepiaria : but there is no real difference in size as
Butlikofer points out. See also Finsch (Notes Leyd. Mus.
XXII, p. 220) who finds the wings to vary indiscriminately
from 65 to 74 mm. as I do.

Except on the heads the colour differences given by
Meyer are not visible in the freshly collected series.

" Iris, adult male yellowish white, immature birds dark.
Bill black, tip and gape whitish in immature birds. Feet
black."

The immature specimens lack the spangles on the head
and breast and have no frontal hairs, shoulder plumes or
curled tail feathers.

The colour and plumage characters of this bird are
exactly those of C. hottcniolta (which occurs on the
(^.ontinent as far south as South Tenasserim and Cochin-
CJiina only ; for this species is another instance of that
interesting anomaly in distribution in which a number of
species common in Indo-C.hina are absent in the Malay
Peninsula, but appear again in Java and sometimes in
Borneo and Sumatra) and apparently of lencops, Wallace,
of Celebes and pectoral i.s Wallace, of* the Xulla Islands. In
the shape of the bill it agrees with the two last, the bill
being higher, less tapering and more keeled than in con-
tinental birds : it is in fact the bill of the so-called
Dicruropsis smnatniniis (Wardl . Rams.) somewhat
elongated ; and larger of coui'se, to agree with the size of
the bird. Except for larger size and perhaps a propor-
tionately slightly lieavier bill, it scarcelv differs from
l)(>rneen.sis Sharpe.

The iris is yellowish while, lluis closelv agreeing with
lencops.

I cannot definitely determine the form for lack of
material and literature : from the Thousand Islands at the
N.W. end of Java termeuleni has been described l)y Finsch
and from Kangean Id., at the N.E. end, jentinki, bv
Vorderman.

222 Journal of the F.M.S. Miiseiins. [Vol. X,

The specimens constitute a new record for Java. I
Jiave no hesitation in including them in Chihia for there
seems to me no reason why those birds which have been
placed in Dicniropsis should be excluded from the earlier
genus : all link up too closely to be separated. Sharpe long
ago expressed the same opinion with regard to the genus
of these birds (P.Z.S. 1879, p. 247).

Since Mr. Stuart Baker published the results of his
studv of continental material of the species Chihia
hoitenlotta (Nov. Zool. XXVI, 1919, p. 44), I have been
able to examine, side by side with the specimens in the
F.M.S. Museums, the collection of these birds belonging
to the Indian Museum.

On the whole this material confirms Baker's
conclusions (except that being smaller the series shows a
smaller range in dimensions and presents one or two
anomalies'), viz., that in the North of India from the
Northwest to the Eastern Himalayas and Assam — and
perhaps North Burnia and the Shan States the birds are,
on the whole, larger ; whereas in Bombay, Central India,
Bengal, South Burma and Siam to Cochin-China and Annam
they average not so large.

But investigation of material should go hand in hand
with investigation of literature and Baker has omitted a
study of the latter. It is certainly a less interesting pursuit.

It is open to anyone to select a type locality for a form
which has been described without one and often, of course,
it is largely a matter of chance whether the choice made
is anywhere near correct : but the selection should at least
have the appearance of probability. As the type locality
for a bird known to Brisson and Lumeus Sikkim seems so
improbable .that the fixation may be tlisregarded.

But in this case there is another reason for rejecting
it. As a type-locality the region including Sikkim io
preoccupied. Baker considers birds from Nepal, Sikkim
and Bhutan to be alike and the Nepal bird has bc'n described
by Gould as Edolius chrishna (P.Z.S. 1836, p. 5) and by
Hodgson as Edolius casia (Indian Review, 1, 1836-7, p.
324). Until the longer-winged, longer-billed northern birds
are separated into races by some reviser the name they must
all beai* is Chihia hottrntoita chrishna (Gould) .

Other places which are perhai)s debarred from selection
as tyi>e localities of the original form are Borabhum and
Dholbhum, Chota Nagpur, (Criniger splendens llckell,
Journ. Asiat. Soc. Bengal II, 1833", p. 574) ; and Bengal
(Calcutta), the locality given by Latham for his Crishna
Crow (Gen. Hist. Birds, III. 1822, j). 51, pi. XI) which is
the same as Edolius harhatus Grav (Zool. Misc., 1831,
p. 34).

J'or the IjTpe locality of Chibia h. hottentotta I select
Siam. As in the case of Cuciihis (Dissemiiriis) paradiseus.
Linneus based the species on Brisson who recorded Siam
as the native country of the latter bird. In Journ. Nat.
Hist. Soc. Siam, Illf 1919, p. 453, I restricted the type
locality to the region between Ayuthia and the head of the
Gulf and now select the same district for C. h. hottentotta.
Mr. W. J. F. Williamson has obtained specimens from near
Bangkok (t.c.s. p. 45) .

As thus localised C. h. hottentotta comes nearest, of
recognised races, to C h. brevirostris of China (type locality
Chusan), but has a rather longer bill, but somewhat shorter
wing.

It seems that there are (1) in the north a larger bird
with (a) a large bill in the Himalayas (chrishna Gould)
and (b) a. small bill in China {brevirostris Cabanis) : (ii)
in the south a rather smaller bird with a bill of intermediate
size {hottentotta Linn.). Whether the bird of Bombay and
Central India in distinct requires, as Mr. Baker says, a larger
series than is available to show. I fancy it is not : the few
measurements given are well within the range of a series
from Burma and Siam.

Thus we have on the Continent at present : —

C. h. hottentotta S. Indo-China and Peninsula India.

C. h. chrishna Himalayas, etc.

C. h. brevirostris I^astern China.

MALAYSIAN CROWS.
CORVUS CORONOIDES.

To a number of the " Verhandlungen der Ornithologis-
chen Gesellschaft in Bayern," received only recently, Dr.
Erwin Stresemann contributes a long and interesting paper
oq the forms of the groups Corvus coronoides Vig. & Horsf .
(Band XII, Heft 4, May 1916, pp. 277-304).

The following is a rough translation of the parts with
which this note deals : —

(p. 284). Corvus coronoides andamanensis Beavan.

Corvus andamanensis Beavau ex Tytler MS. [Ibis 1806, p. 420 —
.\ndamaus : nomen nudum !] Ibis 1867, p. 328 — Andamans.

Like C. c. intermedius, but on the average with shorter
wings and a longer, higher bill. Base of feathers in adults
more or less pronounced white, never grey.

Length 'of wings : Assam : 328, 337. Upper Burma :
294-343 (6 examples) 2. Tenasserim : 279-343. (Average

Peninsula also though no examples seem as yet available.
iVll crows which I have seen in Museums from the Malay
Peninsula and those which I shot in Perak myself were
Corims enca compilator Richmond. It is, therefore, not
clear how one should regard the " Corvus macrorhynchus "
which Robinson and Kloss record in Ibis 1911, p. 71, as
" very abundant in Trang and also in Langkawi and
Terutau " especially as these investigators add the astonish-
ing remark " From Perak southwards to Johor the Slender-
Ijilled crow, Corvus enca Horsf., occurs, but is very rare,
only three or four specimens having been obtained " ( !) . A
transfer of names between the two species appears to me
as not improbable.

of different shape : bill at the base about as high as over
the nostrils. Base of the feathers in adults always white,
in young birds brownish wiiite. Iris brown.

Examples from the Timor group do not appear to
completely agree with birds from the typical locality : but
differ in having a shorter bill on the average, clearer white

The subspecies macrorhynchus is shown to have both
a longer wing and a longer bill than andamanensis. The
heights of the bills provide no differential dimensions ; but
as regards shape Dr. Stresemann states that the culmen of
andamanensis has its highest point above the nostril [i.e.,
the profile is arched proximallyj : that of macrorhynchus
is no higher above tlie nostril than at the base [i.e., the
profile is straight proximallyj.

Dr. Stresemann goes on to say (pp. 295-6) : — " It is
very surprising to find that there is a broad space between
the two areas of distribution of the closely allied forms
andamanensis and macrorhynchus : this is— strangely
enough — occupied by a crow of another species, Corvus
cnca rompilator ! In all parts of the latter's range, the
southern half of the Malay Peninsula, Sumatra, Nias,
Simalur. Borneo — so far as reliable reports go ' there is no
representative of the coronoides species as we should
expect ; at least in the southern half of the Malay Peninsula
and in Sumatra which are parts of the old land bridge
from India to Java. This is a case of allied, but

perhaps an error for Corvus enca compilator ! E. S.

heterogeneous species excluding eiich other geographically.
In spite of the broad zone of separation andamanensis and
macrorhynchus liave remained very similar — so similar
that the majority of modern ornithologists declare them
to be identical."

Dr. Stresemann could be accused of manipulating
literature to fit a theory. In stating that no examples of
covonoides seem aviiilable from the northern part of the
Malay Peninsula he ignores our record of specimens from
Trang, etc., where it was very abundant. In stating that
it does not occur in the southern half of the Peninsula he
ignores our next remark. " In the southern half of the
Peninsula it is scarcer being only seen in numbers on the
coast in the vicinity of fishing villages." This last does
away with his " broken land bridge " theory !

And when he wrote " From Perak to Johor the Slender-
billed Crow, Corvus enca occurs, but is rare, etc." and
suggests (as I understand), that we have transferred the
names of two species he stultifies himself — for if he believes
that our enca of the Southern Malay Peninsula is coronoides
he himself builds a bridge which he later demolishes.

There is no break in distribution — as far as the Penin-
sula is concerned.

Why is our opinion astonishing that (lorvus enca is rare
in the Malay States ? It is based on the experience of good
many years : rather there is ground for astonishment that
in probably little more than as many days in the counti*y
Dr. Stresemann found it, by inference, common.

As to Borneo and Sumatra Dr. Stresemann makes the
same suggestion regarding the birds determined by Finsch
and Stone as he does about our identification. Personally
1 have only seen examples of C. enca from these two islands,
but it seems to me that, for the present, negative evidence
is little better than no evidence.

I'he conclusion arrived at by Dr. Stresemann's methods
is that only one form of C. coronoides, viz., andamanensis,
occurs in the Malay Peninsula, and that the species (apart
from its occurrence at Penang), may extend from Burma
to the northern part of the Peninsula only. Also that
Corvus enca compilator is the common form.

I will now proceed to give some account of the
Malaysian specimens of Crows at present in the F.M.S.
Museimis and, as no instructions have ever been given to
our collectors to discriminate betN\ een the two species when
procuring examples, it may be taken that the numbers
secured fairly represent the rarity or commonness of the
two birds. They show that as far as our experience goes
we can repeat our former statement that coronoides is the
commoner bn-d and in some form occurs tliroughout the
Malay Peninsula.

Twenty-six examples of coroiwides against six of enca
(vide postea) from the same area !

The birds of the Malay Peninsula have both the larger
wing and longer bill ranges of macrorhynchus and must,
I think, be placed under that name, for as regards the forms
of the bill the ditferences stated by Dr. Stresemann do not
seem to hold : I find both shapes in the Malayan series
and of the three Javan birds one has the bill higher at the
nostrils than at the base, while in the other two, the height
at both places is the same.

My conclusions are therefore that a form of the species
(^.oruHs coronoides occurs throughout the whole of the
Malay Peninsula where it is much commoner than the
species Corvns enca ; and that south of Tenasserim (say
Lat. 11° N.) it is Corvus coronoides macrorhynchus Wagl.

CORVUS ENCA.

Six specimens have been obtained during the same
period and in the same area as the 26 examples of
C. coronoides recorded above : the apparant occurrence is
therefore, only one to foui\ The detail? are : —

Corvus enca enca (Horsf.) of Java is smaller and the

viewed laterally it is less wedge-shaped, i.e. the profile does

XII. SEVEN NEW MALAYSIAN MAMMALS.

By C. Boden Kloss, f.z.s.

1. Balionycteris maculata seimundi subsp. nov.

Like B. m. maculata (Thos.) of Borneo but witli the
poslorbital processes much less developed ; short and obtuse
instead of pointed and elongated.^

Male. Head and nape black, shoulders and mid-back
mummy brown, rump and sides cinnamon bi"o\cn Under-
parts hair brown, the fur of the abdomen lipped with
drabby white, of the fore-neck very indistinctly with drab.
Ears and menbranes black ; a small tawny spot on the
anterior margin of the ear near the base, another near the
inner angle of the eye and a pale streak near the angle of
the mouth : finger joints tawny and a f(nv small tawny
spots scattered irregularly over the wing membranes. The
imdersurfacc of the fore limbs and the membranes near Ihe
body distinctly clad with whitish hair.

Female. Only ditfers from the male in jjaving no
drab on the fore-neck and less cinnamon brown on the
rump.

Co-types. Adult male and female (skins and skulls)
from the junction of the Tahan and Teku Rivers at
the foot of Gunong Tahan, Pahang, collected by Mr. E.
Seimund on 26 Februarv 1921, F.M.S. Mus., No. 1/21 and
2/21.

Specimens examined. The co-types, and three
alcoholic specimens, viz., a female with a young one and
a gravid female : all of which formed a small bimch in the
forest.

Collectors e.vlernal measurements of nude and
female : head and body, 57, 57 ; forearm, 43, 42 ; hindfoot,
9, 9 ; ear, 9, 9 mm.

Skull measurements : greatest length, 22 -5, 22-4 ;
condylo-basal length, 21 • 1, 21 • 1 ; palatal length, 11 • 0, 11 • 2 ;
maxillary tooth row including canine (alveoli) 7-0, 7-0 ;
interorbital breadth, 5-2, 4-8 ; breadth across postorbital
processes, 7-3, ()-5 ; breadth of braincase, 10 2, lO-O ;
zygomatic breadth, 15-6, 15-1 mm.

Remarks. Until last year the two Cynoplrrine genera
Balionycteris and Dyacopterus were only known from
Borneo where each is represented by a single species,
B. maculata (Thos.) and D. spadiceus (Thos.). In Ann.
and Mag. Nat. Hist. (9) \, 1920, p 284, Mr. Thomas
described a race of the latter, brooksi, from specimens
collected near Bencoolen, Sumatra, by Mr. C. J. Brooks
and now we have discovered the former in the Malay
Peninsula. We may reasonably' expect to meet someday
with Dyacopterus in the Peninsula and Balionycteris in
Sumatra.

2. Petaurista punctata sumatrana subsp. nov. (PI. Ill) .

Like P. p. punctata of the Malay Peninsula but much
less flecked with white : the spots being almost absent on
head, neck, shoulders, rump, thighs and basal part of tail.

Skull generally similar but rostrum broader and
shorter : zj'^gomata noticablj' broader and more bowed
outward anteriorly ; but interpterygoid space and basi-
occipital narrower : loothrows not converging anteriorly.

Type. Adult female, skin and skull, from the Padang
Highlands, West Sumatra (probably near Fort de Kock).
Obtained by E. Jacobson on 29 Mav 1918. Original number
E. J. 398.

External measurements taken in the flesh : head and
body 345 ; tail 375 ; hindfoot 65 ; ear 29 mm.

SIxull measurements : greatest length, 62-3 (63-0)^ ;
basilar length, 51-0 (50-5) ; diastema, 13-2 (13-2) ; upper
tooth row, 13-9 (11-0) ; interpterygoid breadth, 51 (0-2) ;
breadth between bullae, 9-0 (11-0) ; anterior and posterior
breadths of combined nasals, 11-4, 7*7 (10*5, 6-9) ; median
length of nasals, 17-0 (19-0) ; zygomatic breadth, 42-0
(42-0) ; mastoid breadth, 32-5 (33-0).

Remarks. This is the first time this interesting
squirrel has been taken in Sumatra. P. punctata seems to
be a rare animal everywhere. Other forms have been
described from S. Yunnan {marica Thos.) and the Chin
Hills {sybilla Thos.). Apparantly a mountain species.

3. Sciurus notatus tamansari subsp. nov.

Like the animal inhabiting the lowlands of East Java^
but darker and more richly coloured throughout.

Head, body and limbs above less grey, more olivaceous,
the pale parts of the grizzle being ochraceous. Fore and
hind feet darker grey, contrasting more strongly with the
limbs. Ears and sides of head and neck ochraceous.
Underparts darker, nearly ochraceous-orange. Tail more
richly coloured both above and below, the lower median
line like the under-body.

Type. Adult female (skin and skull) from Tamansari,
Idjen Massif, 1,600 ft., about 15 miles westwards from
Hanjoewangi, East Java. Collected on 18 January 1920
by C. Boden Kloss. Original No. 8,634 : F.M.S. Mus. No.
34/20.

External measurements taken in the flesh : head and
body, 200 ; tail, 185 ; hindfoot s.u., 45 ; ear, 18 mm.

'Measurements in parentheses those of an adult male from
the Larut Hills near Taiping, Perak, 2,100 ft., F.M.S. Mus. No.

Specimens examined. Five from the type-locality

Remarks. This form possibly closely resembles S. n.
stresemanni Thos. of Bah (Ann. & Mag. (8) XI, 1913, p.
503) ; but it has very conspicuous orbital rings and the head
is apparantly less ochraceous.

All recent writers on Sciurus notatus —Thomas,
Bonhote, Robinson and Wroughton — have treated the old
names which have been given the species as synonyms of
S. n. notatus ; and to put matters on a clear footing I select
Western Java as the typical locality of hadjing, Kerr (1792)
and biliniatus Desni. (1817) : we know that nohdus Bodd.
(1785), plantani Ljung (1801) and andrewsi Boidi. (1901)
came thence. And though dschinschinus Gm. (1788) and
gingianus Shaw (1801) are bjsed on the " Ecuriel de Gingi "
of Sonnerat, supposed to have come from Pondicherry,
I have little doubt but that they also are notatus squirrels.
If so — typical locality West Java.

Therefore, of this squirrel, we haNC in Java at
present : —

S. n. notatus (with synonomy as above) West Java.

S. n. balstoni Mid Java.

S. n. tamansari Idjen Massif, East. Java.

All the notatus squirrels I have yet seen fiom West
Java are grey-bellied animals, though the axillae and in-
guinal region are generally butty or tawny : all the East
Javan specimens 1 have examined are entirely butf or
tawny beneath. S. n. balstoni from South Mid-Java is
described as " below pinkish-butt", but as the hairs have
long black bases this colouring is much disguised except
on the inner sides of the limbs where the hairs nrc entirely
butt' " (Robinson and Wroughton, Journ. Fed. Malay States
Mus., IV, 1911, p. 234. Tjihtjap).

5. Sciurus nigrovittatus besuki subsp. nov.

Like -S. n. nigrovittatus Horsf. of West Java' but with
the underparts a less clear grey, the tips of the hairs less
white being often considerably sullied with butt'. Muzzle,

Seven of the latter come from West Java (Wynkoops

is the lowland and sub-montane form throughout the whole

submontane form throughout Java while R. b. treuhi is
found on the mountains at higher altitudes.

The pelage is much less profuse and is stifTer than in
the mountain representative ; but 1 do not regard this as
a racial character for if individuals of the mountain form
were transferred to the plains they, or their first offspring,
would probably at once assume the more spin>, less furry
coat of the lowland animal.

XIII. NOTES ON SOME MAMMALS FROM SUMATRA.

By E. Jacobson.
(Plate III).

In the Journal of the Federated Malay States Museums,
Vol. VII, Decemher 1919, Messrs. H. C. Robinson and C.
Boden Kloss published some papers on mammals obtained
by me in difiercnt parts of Sumatra (pp. 257-291, 299-323).
Below I give some additional data regarding these
collections. Some hares I obtained at a later date have
also been described by Mr. Boden Kloss and myself (tom.
cit. pp. 293-298).

1. Nesolagus netscheri (Schleg.).

Of the extremely rare Sumatran Hare J obtained
altogether seven specimens. Besides the four specimens
enumerated by Mr, Boden Kloss on page 296, I caught : —

One specimen at Balun, in the District of Muaro Labuh
(Padang Highlands), July 1914.

Two specimens at Sungai Kumbang, at the foot of
Korinchi Peak, August 1915.

These three specimens were sent to the Leyden Museum
of Natural History, Of the four specimens examined by
Mr. Kloss three have been sent also to the Leyden Museum
and one has been presented by me to the British Museum.

Where such a rare species is concerned, it is worth
while to record all specimens which have been obtained.

In August 1895 a living specimen was bought by the
Zoological Gardens at Amsterdam from a sailor, who had
obtained it at Padang (West coast of Sumatra), the exact
locality where it came from being imknowji. The animal
was in very bad condition and had lost one of its hind-legs.
At the Zoological (lardens it was fed with bran, radishes,
carrots, bread, young shoots of oak, elm, and beech. Very
soon after its arrival, in September of the same year, it
died liaving remained always very shy and timorous. The
skin and skull are preserved in the Museum of t!ie Gardens.

The Leyden Museum received in August 1916 a skin
and a skull of Nesolagus netscheri from Mr. Stolz at Surian
(District Alahan Pandjang, Padang Highlands), a place
not so very distant from Balun, where I obtained my tirst
specimen.

The Zoological Museimi at Utrecht possesses two
specimens of the Sumatran Hare preserved in spirits.

" Another specimen of N. netscheri, is in the possession
of the British Museum (Natural History) ; and I am
informed by Mr, Oldfield Thomas that Dr. Forsyth-Major
made use of it when writing his well-known paper on
Leporidae. The example is said to have come from Padang,
but this is most certainly not correct and probably due to

236 Journal of the F.M.S. Museums. [Vol. X,

the careless manner in which the collecting locality is often
indicated by laymen. The specimen cannot have come
from Padang or its direct surroundings for the same reason
(pointed out by me in the Journ. F.M.S. Mus. VII, p. 293)
that the type specimen cannot have been caught at Padang
Pandjang. I presume that it was obtained on same coffee
estate in the Barisan Mountains and from there sent to
Padang."

This brings the number of specimens in Museums,
as far as I have been able to ascertain, to a total of thirteen.

is this Journal is : —

skull of the type in three aspects. C.B.K.].

2. Arcionyx collaris hoeveni (Hubr.).

In Messrs. Robinson and Kloss' paper the measurcmonls
of the female specimen (No. E. J. 116) I obtained in the
forest near Suban Ajam (Bencoolen) were not given. I
therefore state them here :

Head and body, 580 ; tail, 160 ; hindfoot, 91 ; ear,
31 mm.^

3. Mydaus javanensis (Desm.) subsp. javanensis ? (Syn.

Mijdaus meliceps, Cuv.).

In the list of Sumatran mammals given by Messrs.
Robinson and Kloss (Jouni. F.M.S. Mus. VIII, Part II,
1918, pp. 73-80) Mydaus javanensis has been left out.
This animal is rather common in Bencoolen from the coast
up to a great altitude in the interior. Mr. Westenenk, when
Resident of Bencoolen, shot one in his garden at the town
of Bencoolen (sea level) and several more were killed by
his dogs at Kapahiang, higher up in the Barisan Mountain
Range. When I was at Suban Ajam at the foot of Mt.
Kaba (Bencoolen) at 1,200 metres (3,700 feet) I noticed
the smell of one of these animals in the forest near our
camp. The odour is not to be mistaken and is so powerful

* The skin of this specii;ien was unfortunately destroyed by
insects ; the skeleton and skull are now in the Leyden Museum
of Natural History.

From my collections of jnammals from Bencoolen, Palembang,
South-West Sumatra, and the Ophir Districts described by Messrs.
liobinson and Kloss besides the specimen of Arctonyx collaris
hoeveni mentioned above, nine more skins have also been destroyed
by insects, viz. : —

Pithecus melalophos melalophos, No. EJ. 23 ; Felis marmorata.
No. EJ. 214 ; Felis beiigalensis sumatnma, No. EJ. 70 ; Pagiuna
larvata leiicomijstax, " No. EJ. 196 ; Gijmnui i gymnura
(jymmira. No. EJ.57 and 77 ; Petaurista petaurista batuana. No. EJ.
34 ; Batiifa bicolor palliata, No. EJ. 90 and 161.

The remainder of my collections has been sent to the Leyden
Museum of Natural History, except a number of specimens
presented to the Federated Malay States Museums.

that it can be conipared with nothing else in Malaysia. In
different parts of Sumatra the animal is called tclegu.
Curiously enough, it does not occur in the Padang
Highlands.

4. Felis tigris sondaica Fitzinger.

There has been some controversy over the question
whether the Sumatran species ought to be separated from
the Javan one. It is therefore interesting to mention the
opinion of Mr. B. Ledeboer, the well-known tiger hunter.

I translate here some of the most important passages
from one of his letters to me :

"The different kinds of tigers distinguished by the

" Javanese, (known as gemhol and tjantel) because of the
" shape of the stripes, are quite fictitious. The skins I
" possess from Java, Bali and Sumatra, more than one
** hundred, all show the same kind of stripes. The slight
"■ diftcrences noticeable being due to age or mode of hfe.
" Tigers living in lalang fields are lighter in colour than
" those from the forest. Young tigers are different from
" old ones. The older the animal, the narrower and further
" apart the stripes will grow. In very old tigers the stripes
" on the front |)art of the body disappear altogether.

" The Sumatran tiger is marked quite differently from
" the Javan form. If a Sumatran tiger is laid on its back,
" nothing is seen but a whitish skin, the under-side of head,
" throat, breast and belly being totally without markings.
" In the Javan tiger, however, the extent of white on the
" under-surface is considerably reduced and encroached on
" by the ends of the stripes from the sides. An animal from
" Sumatra may therefore be distinguished at a glance from
" one from Java. Moreover the stripes in the Sumatran
" tiger are not so continuous, being frequently broken ; they
" even show a tendency to form spots, not plain ones, but
" cuxles. Full grown tigers from Java, Bali and Sumatra
" do not vary much in size. The biggest example I have
" obtained ran somewhat over 3 metres ; 3.05 metres is an
" exception. The males are much larger than the females."

[When Mr. H. C. Robinson and I wrote our note on
Sondaic tigers (Journ. F.M.S. Mus. VIII, pt. 2, 1918. p. 8)
we had to depend on literature for information and recorded
a Sumatran specimen as F. t. sondaica though Schwarz
had selected Java as the type-locality for that race. During
my visit to Java in 1920 I saw a number of tiger bkins from
that island and from Bali and am now of opinion that
sondaica must be used for the Javan animal only, for
besides having the narrower white undersurface mentioned
by Heer Ledeboer the stripes are undoubtedly less heavy
than in the Sumatran animal. The Sumatran and Malayan
material I have been able to compare is very small and
I have not been able to see any difference between the
animals of the island and the peninsula : both apparantly
are F. t. tigris.

238 Journal of the F.M.S. Museums [Vol. X,

The tii^cr of Bali, P. t. halica Scliwarz (Ann. & Mag.
Nat. Hist. (8) X, 1912, p. 325) seems to me to have still
narrower and fewer stripes than the Javanese race (four
Bali specimens examined). Schwarz who only saw one
skin, says the markings are broader and more duplicated !
He also states that the Bali animal is recognisable by its
smaller size. I think that size and skull characters are
very untrustworthy guides for distinguishing Malaysian
tigers : they depend so much on age as we have shown
(I.c.s.) C. Boden Kloss].

5. Fells pardus Linn.

It has sometimes been doubted whether the panther
really occurs in Sumatra, but Mr. Boden Klos« drew my
attention to a record of Schneider, who saw a black panther
at Batu Bahra, and he himself knows of a second animal
fired at, but missed in the Besidency of Sumatra's East
Coast some 1.5 years ago. I myself have been told several
times of black panthers having been shot by Euroi)eans,
and native hunters informed me repeatedly that a black
l)anther, which they called kumhanq was known to them.
In .lava where the same name is applied to the melanistic
variety of Felis pardus, it is much rarer than the normally
coloured animal. I know, how^ever, of no authentic record
of a Felis pardus of the normal yellow colour with black
markings having been obtained in Sumatra. Over and over
again F^uropean hunters assured me that they had shot such
an animal, but on closer investigation all these cases turned
out to refer to Felis nebulosa, the " rimau dahan " of the
Malays.

My opinion, that the normally coloured Felis pardus
does not live in Sumatra is still unshaken, and I am very
much inclined to believe that the black animals shot or
seen in this country are nothing else than melanistic
examples of Felis nebulosa. I may mention, that this is
also the opinion of the well-known tiger hunter Mr. B.
Ledeboer.

7. Petaurista punctata sumatrana Kloss (Plate III) .

This specimen, which will be sent to the Leyden
Museum, was bought from a native at Fort de Kock (940
metres), and nuist have been captured in the vicinity' of
this place, situated in the Padang Highlands (West coast
of Sumatra). It had become rather tame and was kept
in a cage. Being of nocturnal habits it slept mostly during
the day, sitting hunched up in one of the corners of its
cage, with its tail folded over its back and the end of it
curled around its iiead in such a manner, that the latter
was entirely concealed. If disturbed during *he day it
would wake up for some time and even take the food given
to it, but later it would go to sleep again, becoming lively
in the evening aftei- the sun had set. A favorite position
when awake was the one seen in the accompanying photo-
graph, its tail being held over its back and head.

The Prtanri.sUi was fed witli all sorts of fruit and
nuts, tile tigs of ditferent kinds of Ficn.s beuig very much
preferred. 1 think 1 made a great mistake by feeding it
exclusively on vegetable matter, as it is well-known that
squirrels are great destroyers of birds nests, devouring eggs
and yound tledglings. The idea did not occur to me then
to provide animal food, and to this reason I ascribe the
fact that the Pelaurista after some time began to gnaw its
soles. After it had devoured a great part of the skin of
its feet, I decidetl to kill the animal, fearing the specimen
would be spoilt.

Afterwards I heard from one of my acxjuaintances,
that he had kept a Pclaurista in confinement, which
devoured the greater part of one of its gliding membranes.
The natives here assert that the Petaurista, which is called
in Minangkabau Malay kubiu\ destroys the very young
coconuts, not bigger tiian a hen's egg, but the specimen
I kept refused to touch these young nuts.

Petaurista petaurista batuana Miller, seems to be the
common species in the Padang Highlands. When I once
stopped at a village called Andalas at the foot of Mt. Sago,
tlying-squirrels used to come ;'t dusk in a volplaiie from the
surrounding hills down to the village in the vallev, covering
in one stieUh a distance which must have been at least 400

' The name of kiihin is equally applied to the flying Lemur
(idleoptenis variegatiis tcnimincki (Waterh.). [hi Sumatra,
perhaps, but in tlie Malay i'eninsiila tliis animal is called " kubong "

240 Journal of the F.M.S. Museums. [Vol. X,

or 500 yards. They alighted always on Ihe trunks of
coconut trees, which being totally without branches afforded
a convenient alighting spot. Then they crawVd up the
trunk till they came underneath the base of the crown and
pushed off, alighting then on some other tree. The line of
flight is always curved ; first slanting down and then curving
up again : the point of arrival is, however, always lower
than the starting point.

When in August 1015 I made an ascent of the Peak of
Korinchi (Sumatra), I found a PeUmrista on the highest
point of the Peak, at the very brim of the crater. When
I approached it stared at me with its large glaring eyes,
making no attempt to escape.

I cannot explain what motive the animal had to seek
such an inhospitable spot, which is 3,800 metres (12,500 ft.),
high and, except for a few straggling plants, is for the last
400 metres entirely bare of all vegetation. The animal
could not possibly have come to the mountain top through
the air, for, as pointed out above, it has to avail itself
always of a higher starting point. Therefore it must have
crawled up all the way from the nearest .forest, which is
still considerably below the limit of vegetation.

This is not the only record of a Petaurista being found
in such a peculiai' place. Mr. L. Westenenk, now Resident
of Palembang, told me that a Petaurista was formerly seen
at the edge of the crater of Mt. Merapi in the Padang
Higlilands. The surroundings of this crater are also
'vithout vegetation.

XIV. NOTES ON THE PROBABLE CLIMATE OF A
MOUNTAIN STATION IN THE MALAY STATES.

By C. E. p. Brooks, m.sc, Air Ministry.

1. Temperature.

The heat of tropical regions is proverbial, but they
are characterised rather by constant heat than by unusually
high temperatures. Taking Singapore as an example, and
comparing it with Richmond, Surrey, we have the following
little table :—

Temperature. Singapore. Richmond.

"F. °F.

Mean annual
Hottest month
Coldest month
Annual range
Mean daily maxinunn
Mean daily minimum
Highest recorded
Lowest recorded
Absolute range

Average difTerence between mean tem-
I)erature of one day and the next . .

This table shows us at once the characteristics of an
etiuatorial coast station as comi)ared witii London :

(1) The mean annual temperature is about 30 degrees
higher. On all tropical coasts and islands the mean
temperature at sea level stays very close to 80° F., a round
number which is very convenient to remember.

(2) The annual variation is exceedingly small, being
only 2° F. at Singapore. At stations so close to the equator
(the latitude is only P 17' N.) it is more oi less of an
accident which months are the warmest. There is no
distinction of seasons by temperature as there is in England,
the terms " winter," *' spring," etc., having n'^* meaning.
The sun is overhead at the equinoxes, i.e., March and
September, but the difference from other months is not
great enough to be im]K)rtant.

(3) The daily range, or the difference between the
temperature of the day and that of the night, is very nearly
the same at Singapore and London, but even here there
is a difference. In the tropics the day is alMays hotter than
the night by about the same amount, and the alternation
of higher and lower temperatures every 24 hours is as
regular as is the alternation of summer and winter in
temperate regions. In fact it has been said that " night
is the winter of the tropics." In England on the other
hand, though the day is generally warmer than the night,
it sometimes happens, especiallj'^ in winter, that the tem-
perature rises as night comes on, so that the night is
warmer than the day. In the tropics this never happens.

242 Journal of the F.M.S. Museums. [Vol. X,

(4) But though the night is cooler than ti.e day, it U
still very hot, as judged by English standards. 74° F.,
which is the average temperature of the coldest part of the
night at Singapore, would pass for a hot day in England.

(5) It is in the extremes of temperature that the
difference between temperate and equatorial regions is
shown most markedly. Days almost as hot as any met
with in Singapore can be experienced in a L.ondon summer.
At Bukit Mertajam, near Perak, a maximum temperature
of 101° F. has been recorded, but this has been nearly
equalled in England (100° F.). On the other hand, the
lowest temperature recorded at Singapore is 70° F., while
at Richmond the thermometer has been down to 9° F., a
difference of 61.^

(6) The smaller difference from one day to the next
in the Tropics also makes for monotony.

2. The Change of Temperature with Height.

Leaving the sea-level- and climbing the slopes of a
mountain, the temperature is found to fall. This fall is
on the average at the rate of about 3 degrees Fahr. for
every tliousand feet. Thus at a height of five thousand feet
the mean temperature will have fallen from the tropical
figure of 80° F. to the merely pleasantly warm one of 65° F.
That is why it is always desirable in the troj)ics to establish
health stations or sanatoria on high mountains, the change
to the lower temperature having a marked bracing effect ;
the smaller density of the air owing to thf> decreased
atmospheric pressure is also beneficial at moderate
heights (not exceeding 6-7.000 ft.) as in the generally
greater dryness of the air.

The diurnal range at high levels does not generally
diifer greatly from the average at lower levels, but much
depends upon local conditions. On an elevated plateau the
range is much greater than on the side of an isolated moun-
tain peak, for two reasons. Firstly, a plateau offers a wider
surface to direct heating by the sun's rays, and therefore
gets much hotter during the day than a mountain slope.
Secondly, on a level plateau the air becomes colder at night
than on a mountain slope. Air, especially div air, does
not itself lose heat rapidly by radiation, but the ground
beneath it does, and the air becomes cooled by contact with
the ground. Consequently air near the ground becomes
colder than that some distance away from the ground.
Gold air is heavier than warmer air, consequently it will flow
down a mountain slope like a river and give place to warmer
air which has not been in contact with the ground. On a
plateau it cannot flow away, but must remain v.here it is,
so that the temperature falls lower.

This is illustrated by the contUtions at tw > mountain
stations in Java. One, on a level plateau enclosed by the
Yang Mountains, at an elevation of 6,500 ft., has a daily

1921] Brooks : Mountain Climates. 243

range of 14" F., from 66° F. in the day to 52° F. in the
night ; at the other, at Tosari on a mountain blope, at a
height of 5,800 ft., the daily range is not more th.-n 7° F.

At Tosari in Java the lowest temperature occurs just
before sunrise, as near the sea coast, but the temperatures
during the day at a height of about 5,800 ft. are very
different. In the morning clouds form with their upper
surface below the level of the station, and temperature
rises rapidly, the station receiving not only tliC direct and
very powerful radiation from the sun, but also that reflected
from the clouds. But during the day, as the heat of the
plains becomes greater, the level of the clouds rises, and
shortly after ten o'clock they reach the station, which then
becomes plunged in mist. Temperature now faUs rapidly,
but with great fluctuations of as nuich as 5° F. in a few
minutes as the clouds come and go. Consequently the
greatest heat of the day comes about ten o'ckck in the
morning, instead of in the afternoon as at lower levels. The
afternoons are cloudier and cooler.

As a rule, at night the clouds either dispcse or sink
to a lower level, so that the nights are clear and dry, but
occasionally they will be cloudy and these nights will be
relatively hot and oppressively moist, the blanket of cloud
preventing the ground from radiating its heat.

3, Humidity, Sunshine and Cloudiness.

The chief characteristic of the humidity of tiie air at a
tropical mountain station is the rapidity with which it
varies. Above the clouds the air is very dry, but among
them it is satiuated with moisture. In the intense solar
radiation of the morning the air is as dry as thai of a desert
at noon ; a cloud drifts up, and even though no rain falls,
everything drips with moisture. The actual average
depends upon local conditions, but will probably be not
far from eighty per cent, of saturation during the days — a
figure indicating a quite considerable degree of moisture,
and much less during the nights, which would thus appear
cooler than they actually are relatively to the plains.

The amount of bright sunshine will probably be very
considerable. At low level stations the sky is on the average
half covered with clouds, which means that on the average
sunny and dull days will occur with equal frequency, but
at a level of 5,000 ft. much of the cloud development will
take place below the station, which will thuG receive a
greater amount of sunshine, especially in the mornings.
Moreover, owing to the greater clearness of the air, this
sunshine will be far more powerful than on the plains.
Excess of sunshine and light is frequently dangerous to
Europeans in the tropics.

4. Winds : The Alternation of Monsoons.

But if there are not four seasons in the English sense,
there is a very definite division of the year into two seasons

244 Journal of the F.M.S. Museums. [Vol. X,

of another type, known as the north-east and south-west
monsoons. From December to March the wind blows very
regularly from the north-east, and from May to October
it blows almost equally regularly from between south-east
and south-west. April and November are transition
months.

To understand this change we must consider the
geographical position of Singapore. To the north lies the
great continent of Asia, to the south the large island of
Australia. These are far enough north and south to be
greatly cooled in winter and to a less extent heated in
summer. Lying in opposite hemispheres, Asia is hot while
Australia is cold, aiul nice nersa. The equatorial regions
are always hot. Now air expands with heat, and hot air
is lighter than cold air, consequently hot air tends to rise
while the cold air tlows along the surface of the earth to
replace it. In the months of November to March this cold
air flows in a steady stream of immense volume from the
high table lands of central Asia, where it is winter, across
the inter\'ening oceans to the equator and possibly beyond
it. This is the north-east monsoon, which returns every
year at about the same time. In some parts of the worjd
it blows with great force, but at Singapore it is relatively
light, blowing at only about two miles an hour a few feet
from the ground.

From May to October it is Australia that is relatively
cold, and the wind at Singai>ore during these months is
away from this continent, i.e. is southerly, blowing from
between south-west and south-east at about two miles an
hour. At this sheltered locality calms are frequent but in
a more exposed situation calms are rarer and the velocity
of the wind somewhat greater. Wind generally increases
in velocity with height, and on a mountain slope there is
probably a fairly steady breeze which is a favourable factor
in the climate. The alternation of monsoons at the level
of 5,000 ft. is probably the same as at Singapore, but at
greater heights the wind would come very regularly from
east.

5. Rainfall.

The rainfall in the Straits Settlements is everyw^here
hea\^, Singapore having one hundred inches (2,500
millimetres) a year and Perak as much as 120 inches (3,000
nmi.) . Whether the rainfall at a mountain station of
5,000 ft. height would be more or less than this depends very
much on local conditions, probably it would be rather less,
as the heaviest rain clouds often have their under surfaces
below 5,000 ft. At still greater heights the amount falls
oft' rapidly. A total of one hundred inches is several times
as heavy as that of London, but it must be remembered
that owing to the extremely rapid rate at which rain falls
in the tropics, the actual time taken is ver>' much less. The
intensity of tropical rainfall is only rarely attained in

1921] Brooks : Mountain Climates. 245

England, in exceptionally heavy thunderstorms. The cause
of this heavy rainfall is the great amount of moisture in
the air. Saturated air at 80° F. contains twice as much
moisture as the same volume of saturated air at 60° F., and
nearly four times as much as at 40° F. It is by the elevation
of air and its consequent cooling that clouds and rain are
formed. If saturated air is cooled from 80° F. to 60° F. it
will set free twice as much water, that is, the rain will be
twice as heavy, as if it were cooled from 60° F. to 40° F.
The number of days — 173 — at Singapore is almost the same
as at Richmond (170), and in Perak, although the total fall
is greater, the average number of days is only 156. A
" rain-day " is defined as a day on which a measurable
amount of rain, generally 0 • 01 inch or more falls.

There is some attempt at the development of a rainy
season in the Straits Settlements, but it differs in different
parts. At Singapore the rainiest months are November to
January, and the least rainy — one can hardly call them
dry — May to September. In Perak September to November
are the rainiest months, January and February the least
rainy. Even the relatively dry months however exceed six
inches (160 mm.) in their rainfall, a total representing an
unusually wet month in England.

Some of the individual falls are exceedingly heavy,
Singapore having experienced more than 7 inches (175
mm.) in a day on at least two occasions, while Perak has
reached the total of 13-8 inches (346 mm.) in 24 hours.
But at a mountain station we may expect the falls to be
less heavy and more continuous.

There is one point in which mountain climates in the
tropics are unfavourably situated, and that in the unequal
division of the rainfall between the day and the night, owing
to the daily variation in the level of the clouds. Tosari,
the health resort of Java previously referred to, has an
annual rainfall during the day of about four times as much
as that during the night, and this peculiarity is probably
shared by other mountain stations in the tropics of a similar
height.

6. Storms.

Tosari is very subject to severe storms from the south-
west, but these are local only, being due to the peculiar
nature of the topography of East Java, where a long funnel-
shaped valley conducts the winds with accumulated force
straight to the settlement. An open isolated peak should
be much better situated in this respect, and should rarely
experience more than a strong breeze.

XV. THE FLORA OF KLANG GATES, SELANGOR.

By H. N. Ridley, M.A., C.M.G., F.R.S.

The high ridge of Klang Gates in Selangor consists
of a lofty dyke of quartzite running across the valley of
the Klang river which has cut its way through the rock.
The ridge is about three miles in length, and its highest
point is 1,400 feet in height. In many places the top is
quite narrow, only a few feet across, and the sides are
in most places quite precipitous. It is evidently a
quartzite dyke traversing granitic rocks which have long
since been eroded away. I visited it many years ago
and collected there a portion of the peculiar flora on a
part of the ridge to the north above the bungalow, which
stands high up above the road; and on the 2nd January,
1921, with Mr. C. Roden Kloss and Messrs. Milsum and
South of the Agricultural Department ascended the
ridge on the south side to Rukit Lompat Rayan, 1,148 feet
altitude. On the previous day Mr. Kloss and I
had ascended the north side above the bungalow, for
some way, and later Mr. Kloss went further up
towards Rukit Ratu Tabur, the highest point, 1,445 feet
high. On the lower slopes the lowland flora has ascended
for some distance, where there is sufficient soil and
humidity for its growth, but on the bare quartzite ridge
there is a small but quite peculiar flora consisting of
several endemic species with several only known from
much higher altitudes in our mountains, and not occurr-
ing in the forest-clad hills of the main chain. These
plants are strictly xerophytic and, as I shall hope to show
in a later paper, are the remains of an ancient xerophytic
flora which at one time pervaded the whole of the Malay
Peninsula, but which by climatic changes has been driven
out, only persisting on the sub-xerophytic tops of certain
of our mountains and to some extent on the seashores.

To reach the summit of the ridge on the south side
we crossed the river and passed through a portion of a
rubber plantation, above which is a wooded slope con-
sisting of lowland trees and shrubs in which we found
the new and beautiful Didijmocarpus primiilimis. This
slope of deep humus leads to a break in the precipitous
quartzite ridge by which it is possible to get on to the top
at Rukit Lompat Rayan, which is quite bare of soil and
bears the remarkable rock flora. It is this flora of which
I treat in this paper, but have added two new species
growing lower down and towards the base of the rock.

Capparis lariitensis. King. (Capparidaceae).

A single bush of this very thorny plant occurred on
the rocks behind the bungalow. Only previously known
from Perak.

248 Journal of the F.M.S. Museums. [Vol.X,

Elaeocarpus MastersiU King. (Tiliaceae).

A small bushy tree, the leaves are rather small and
more coriaceous than in the typical lowland form.
Common in open country in the Peninsula.

Rhodoleia Teysmanni, Miq. (Hamamelideae).

This beautiful bush with its heads of rose-pink
flowers is abundant on the rocks on both sides of the
ridge. It is a high mountain plant occurring on the dryer
mountains at 3,000 to 5,000 feet altitude. I have never
seen it at such a low altitude elsewhere.

Pygeum Hookerianum, King. (Rosaceae).

The bush here has smaller and narrower leaves than
usual. Not rare in the low country.

Carallia euryoides, Ridl. Flora Mai. Pen. 1, 1922, p. 698.
(Legnotidae) .

A small tree, branches slender, black with prominent
nodes, leafy at the top only. Leaves coriaceous, elliptic
acuminate with a long blunt point, base cuneate, edge
serrulate, 1.75 in. long, .5 in. wide; nerves 7 pairs strongly
inarching, hardly invisible above; petiole .25 in. long.
Cymes axillary, .25 in. long, of 3 flowers, or compound of
3 branches with 2 flowers on each; pedicels .1 in, long.
Flowers .12 in. long. Calyx urn-shaped with 5 coriaceous
lanceolate acute lobes. Petals very narrow linear 5, as
long as the sepals. Stamens 10, the outer series slightly
longer than the inner row, about as long as the sepals,
the filaments rather thick; anthers elliptic. Style stout
as long as the sepals; stigma rather large pulvinate.
Fruit small, ovoid with the persistent triangular lanceo-
late sepals. On rocks about 1,000 feet altitude. Not
common. Allied to C. Scortechinii King, and montana
Ridl., but the leaves are entirely diff'erent with the general
appearance of those of Eurya acuminata. This set of
Carallias is typically montane and very distinct from the
much larger leaved lowland species which also have
larger cymes.

Boeckea frutescens. (Myrtaceae).

Perhaps the most abundant and conspicuous shrub
on the rocks. This plant is typically a high mountain
plant of the dryer mountains such as Gunong Tahan,
Mount Ophir and Kedah Peak at 3 to 4,000 feet altitude
and is absent from the wetter mountain forests of the
main chain ^ and from Penang. Its occurence on Klang

1. It occurs freely on Gunong Terbakar near Gunong Beruni-
ban in the main range, Perak-Pahang boundary, where there is
a heavy rainfall. H.C.R,

i922] Ridley: The Flora of ICtang Gates. ^9

Gates is very remarkable. It is reported also as a seashore
plant in Borneo and Trengganu \

Anplectrum divaricatum, Triana. (Melastomaceae).

In the lower country a long climber, but here I found
some in the form of a bush.

Sonerila prostrata, Ridl. Flora Mai. Pen. 1, 1922, p. 782.

A very slender, creeping, prostrate plant, stems
filiform, several inches long, hairy red. Leaves in equal
pairs, .5 in. apart, ovate hairy above with sparse wtiite
hairs, tip rounded, base round or shortly narrowed, edge
serrate .25 in. long and wide; petiole slender, 1 in.
long. Flowers 2 on very slender terminal peduncles;
pedicels very short. Calyx urn-shaped narrowed upwards
with short acute teeth, hairy, .12 in. long. Corolla bright
pink, .25 in. wide. Petals 3 or 4, obovate, minutely
apiculatc. Stamens 3, nearly as long as petals; anthers
yellow. Style slightly shorter. Capsule flask-shaped,
smooth, nearly truncate with very short points, .25 in.
long.

On shady rocks at the entrance of the tunnel on the
road at Klang Gales forming a small mat of stems.
This charming plant is utterly unlike any species of the
genus known to me in its prostrate creeping stems and
very small star-like flowers. It is, however, I think most
nearly allied to the slender-stemmed erect group with
smooth fruit, of which S. tenuifolia is an example.

Aleisanthia rupestris, Ridl. (Rubiaceae) .

This is common especially on the rocks above the
bungalow and Klang Gates is its only known habitat.
The only other known species is A. sylvestris Ridl., from
rather dry wooded hills at Kuala Lebir in Kelantan, a
tall shrub. A. rupestris is a dwarf shrub barely 12 in.
tall with yellow flowers.

Embelia coriacea, Wall. (Myrsineae).

A climber with large stiff leaves and big panicles of
small white flowers. It occurs all over the Peninsula from
Singapore to Penang and in Java, Sumatra and Borneo.

Vaccinium eburiieum, Ridl. (Vacciniaceae) .

A very fine bush, or almost a tree, with abundance
of pure white flowers. Also occurs on Kedah Peak.

1. It is also abundant in Lower Siam north of Patelung,
almost at sea level. Great stretches of it can be seen from the
railway. H.C.R.

250 Journal of the F.M.S. Museums. [Vol. X,

Rhododendron longiflorum, Lindl. (Ericaceae).

A beautiful bush Rhododendron with bright red
flowers. On the rocks on both ends of the ridge. It
occurs also in Perak and formerly in Singapore as an
epiphyte on high trees, and in Borneo and Sumatra.

Fagraea auriculata, Jack. (Loganiaceae) .

A single plant on rocks behind the bungalow. Not
in flower, I saw it there on my first visit. This plant
usually starts life as an epiphyte and eventually by
killing its host becomes a tree. It also grows on rocks.
Scattered over much of the Peninsula and the Malay Isles.

Didymocarpus primulinus, Ridl. sp. nov. (Cyrtand-
raceae).

A herb with a short, closely hairy stem about 1 to
4 inches long. Leaves about 6, elliptic, round at tip, base
round or shortly narrowed, above glabrous, beneath softly
densely hairy, edge thickly hairy; nerves 8 pairs, distinct,
1.5 in. long, 2.75 in. wide; petiole 1 to 2 in. long, thick,
densely hairy. Scai)es very numerous, erect, slender
from upper axils one-flowered, 2 in. long, hairy. Calyx-
lobes linear acuminate, .2 in. long. Corolla-tube .5 in.
long, limb .4 in. long, unequally bilobed, upper lobes
oblong, blunt, .2 in. long, lower lip nmcli longer .4 in.
long with 3 broad rounded oblong lobes .25 in. wide. All
primrose yellow with an orange patch in the mouth.
Stamens 2, filaments slender, curved as long as the tube,-
anthers elliptic connivent. Capsule slender, 1.5 in. long,
acuminate, glabrous when ripe.

In woods on the slope leading to Bukit Lompat
Bayan. This pretty plant seems to me to be most nearly
allied to D. longipes Hook, of Mt. Ophir.

Trema angustifolium, Bl. {Urticaceae).

Shrub about 4 feet tall. A clump of this on the bare
rock on Bukit Lompat Bayan. Distrih. Malacca, Penangj
Sumatra.

Ficus nidica, L.

Tree on the high ridge above the bungalow collected
by Mr, Kloss on his second visit. Common in the
Peninsula.

Ficus diversifolia, Bl. var. Kunstleri.

On the ridge behind the bungalow (C. B. Kloss)
usually an epiphyte and as such on lofty trees common
in the Peninsula.

1922] Ridley: The Flora of Klaiig Gates. 251

Ficus diver si folia, var. ovoidea.

A number of bushes on rocks behind the bungalow.
This is usually a seashore form: it is quite erect and
terrestrial.

Choriophylliim malayarmm, Benth. (Eiiphorbiaceae) .

A bushy tree with dark green leaves and greenish-
white flowers. On rocks behind the bungalow, a male
tree. A mountain plant and almost the only plant in the
order which ascends above 2,000 feet.

Eriachne pallescens, Br. (Gramineae).

On rocks near the bungalow, common here. Not
rare in rocky and sandy spots especially near the sea,

truncate at base with a central midrib fairly conspicuous;
ligule none. Spikes one to four, 1.5 in. long with a few
distant reduced leaves. Rachis of spike terete fringed
with white silky hairs, joints tufted silky white. Spikelets
1-stalked and 1-sessile, the stalked one articulate on a
silky fringed stalk. Glumes 1 to III lanceolate narrow,
white hairy, awned from below tip, II is very narrow. III
rather broader. Valve (Glume IV) very short, glabrous
hyaline bifid, lobes acuminate, awn .5 in. long, turning
brown at base, white above. Stamens 3; anthers yellow,
oblong. Style plumed, buff. On the bare rocks at Klang
Gates on Bukit Lompat Bayan.

A very distinct species of this genus which is
represented in the Malay Peninsula by three species
E. lanipes Ridl., of Kedah Peak, E. praemorsa (Polytrias
praemorsa) and E. Ridleyi, Stapf : a sand-hill plant.

XVI. BIRDS FROM THE ONE FATHOM BANK

LIGHTHOUSE, STRAITS OF MALACCA,

November, 1918 and November and December, 1919,

by
H. C. Robinson and C. Boden Kloss.

The One Fathom Bank Lighthouse is an erection on
a submerged bank in the middle of the Straits of Malacca
about fifteen miles distant from Pulau Pintu Gedong,
the nearest point of the Selangor Coast and about
26 miles from the Aroa Islands towards the Sumatran
coast, whence a collection has already been reported on
(Journ. Fed. Malay States Mus. ii, pp 8-14 (1906). This
collection was made during November and is very
similar in character.

The present list adds two birds to the Fauna of the
Malay Peninsula, viz: —

Chelidon dasijpus (Bp.)

Oceanodroma monorhis (Swinh.)

while several species only rarely met with on the main-
land were found in abundance.

With very few exceptions all the specimens were
either killed against the light or captured while fluttering
around it. Species which were obtained on the Aroa
Islands are marked with an asterisk.

XVIL A LIST OF BIRDS COLLECTED ON PULAU
RUMPIA, SEMBILAN ISLANDS,

In November and December, 1918

by
H. C. Robinson and C. Bodhn Kix)ss.

The following list of birds collected by Mr. E. Seimund
on Pulau Rumpia, one of the Sembilan Islands off the
mouth of the Perak River, in November and December,
1918 is of interest as bearing on migration and migra-
tion routes in the Malayan region, regarding which we
have as yet very little exact knowledge.

One bird, new to the Fauna of the Malay Peninsula,
was obtained:

Oreocincia dauma (Lath.)

Pulau Rumpia is a rocky island rising to a height
of about 600 feet and of very uneven surface. In extent
it is perhaps 1,500 or 2,000 acres and is densely forested.
There are two or three small bays with sandy beaches
of no great extent. It is the largest of the Sembilan Group
and is separated from the other islands and from
the mainland by depths approximating to twenty-five
fathoms.

Except during the migration season the bird popula-
tion is small, being confined to a few nutmeg-pigeoq,
crows, sunbirds and an occasional kingfisher, excluding of
course the usual shore and marine birds.

Our specimens from the Malay Peninsula conform

however if they represent other than a non-breeding

JARAK, STRAITS OF MALACCA,

In November, 1919, i

by

H. C. Robinson and C. Boden Kloss.

For comparison with the birds collected on Pulau
Rumpia a collection was also made on Pulau Jarak,
Straits of Malacca, in November, 1919. Pulau Jarak is
a small island, about three hundred acres in extent, rising
steeply from the sea to a height of 600 feet. It is densely
covered with vegetation and has no beaches and is
entirely uninhabited.

Large numbers of a peculiar rat (Rattus rattus jarak,
Bonhote) are found on it and a slightly differentiated
form of a widely spread fruit bat {Pteropus hypomelanus
fretensis, Kloss). As might be expected the birds
obtained are not materially different from those on
Pulau Rumpia from which island Pulau Jarak is distant
about 34 miles almost due west, the maximum depth of
the intervening sea being about 30 fathoms.

Otus liiciae, Robinson & Kloss, Journ. Nat. Hist. Soc.
Siam, v., 1922, p. 111.

A very rufous form of Otus luciae (Sharpe). The
black markings on the crown, nape and tail much reduced
and the spots on the back obsolete : wings and tail strongly
washed with rufous, the outer webs of the wing feathers
scarcely blackened, the pale wing bars much obscured.
The undersurface paler and the spots and vermiculations
obsolete. Differs similarly, but to a less degree, from
O. vulpes. Grant, from Gunong Tahan, 5,000 feet, Pahang.
We are not prepared to accept imlpes as different from
the Kinabalu bird.

Type. Adult female from Kao Nong, Bandon, 3,500
feet. Peninsular Siam: collected on 23rd June, 1913.

A male from Kao Luong, 5,000 feet, in the same
mountain range, differs only in having the black markings
on the head a little more pronounced and in being a
trifle darker beneath.

Compared with one example of O. luciae from N.
Sarawak and seven from the Malay States (O. vulpes.
Grant).

Cyornis anak, sp. nov.

Size as in Cyornis magnirostris, Blyth, but the bill
markedly smaller: males with the breast a deeper rufous
and the blackish-blue of the sides of the neck extending
to restrict the rufous area of the throat to a small A
shaped area falling considerably short of the mandible:
upper parts deeper blue.

Females like those of magnirostris but the under-
parts paler; the abdomen more extensively white owing
to lesser infuscation of the flanks, undertail-coverts
white, the pale area of the throat restricted as in the
males; the upper parts rather browner, less olivaceous.

Type. Adult male from Krongmun, Trang, Penin-
sular Siam: collected on 16th February, 1910. Specimens
examined : the typ.e, a male from Kao Luong, 2,000 feet,
Nakawn Sri Tamarat, a female from Nongkok, Ghirbi
and a female (? vixad.) from Chong, Trang; collected on
23rd March, 1922, 12th January, 1918 and 16th February,
1910, . ^

Compared with two males and two females of
C. magnirostris and a large series of C. caerulifrons
Baker — a much smaller bird. We cannot refer these
examples to any known form and are very reluctantly
impelled to give them a new name.

Kittacincla malabarica interposita, subsp. nov.

Kittacincla macrnrus macrurus, Robinson & Kloss,
Ibis, 1919, p. 596.

Differs from K. m. malabarica (Scop.) of India
and Burma (type locality Malabar) by its darker
female and from K. m. tricolor (Vieill.) of the southern
half of the Malay Peninsula, Sumatra and West Java
(type locality) in having the feathers of the thighs in
both sexes white, hardly tinged with rusty. From this new
race K. malabarica macrourus (Gm.) of Pulau Condore,
off Cochin-China, differs in being paler on the breast in
males and having less black on the outer tail-feathers.

Range. From South Annam and Cochin-China to
Tenasserim and down the Malay Peninsula to about
Trang as far as ascertained.

Type, Adult male from Daban, South Annam:
collected on 14th March, 1918, by Boden Kloss. Wing

XX. ON A COLLECTION OF REPTILES AND

BATRACHIANS FROM THE MOUNTAINS OF

PAHANG, MALAY PENINSULA.

By Malcolm A. Smith, F.Z.S.

The present report is based upon collections made
in two separate, but not far distant localities: — (1) from
Gunong Tahan, the highest mountain of the Malay
Peninsula, and (2) from Eraser's Hill, an area on the
main peninsula range of considerably less altitude, north
of the well-known Semangko Pass, between Selangor and
Pahang, and not a part of the same range, and about 70
miles S.W. of Gunong Tahan.

The bulk of the collection is from the first-named
locality, and was made by the F.M.S. Museums in connec-
tion with the metoorolgical survey of Gunong Tahan
which has been undertaken during the past two years.
I am indebted to Mr. Herbert Robinson, Director of
Museums, for the privilege of examining it.

The following are the chief localities referred to: —

Kuala Teku. The confluence of the Tahan and Teku
Rivers at the foot of the Tahan massif. Height about 550
feet above sea level.

Kuala Tahan. The confluence of the Tahan and
Tembeling Rivers about fourteen miles below Kuala Teku.
Height about 230 feet above sea level.

Wray's camp. A halting place about four hours walk
from Kuala Teku. Height above sea level. 3,300 feet.

Padang. The main station on Gunong Tahan. Height
above sea level about 5,400-5,700 feet.

Gunong Gedong. One of the peaks of the eastern
Tahan range. Height above sea level about 6,400 feet.

All the specimens from Eraser's Hill were taken in
June last, at an elevation of between 3,000 and 4,000 feet.

With regard to the text of the report, the numbers
referred to are those of my own private register.

F.M.P., where used as a reference, indicates
" Boulenger's Fauna of the Malay Peninsula, Reptilia
and Batrachia, 1912."

The claim of Rana lateralis Boulenger, to be included
in the fauna of the Peninsula, (based on a single speci-
men), is shown to be incorrect (see R. miopus).

264 Journal of the F.M.S. Museums. [Vol. X,

Two new forms are described: — -
Rana cataracta
Kalophrynus rohinsoni.

Seven species appear new to the Peninsula: —

Chitra indica (Gray).
Coluber prasinus Blyth.
Polyodontophis collaris (Gray).
Lygosoma indicum (Gray).
Rana miopus Boulenger.
Rana picturata Boulenger.
Kaloula haleata (Mueller).

Zool. Jahrb., 1909, Suppl. 10, p. 608 ; Annandale, Rec. Ind. Mus.,
1912, VII., p. 169,' pi. VI., figs. 1 & 2.

The discovery of this species, one of the largest of
the freshwater turtles, in the Malay Peninsula is a fine
extension of its known range. It has previously been
recorded from the Ganges and Irrawady river systems.

This turtle has also been met with in the Ratburi
river. Western Siam, two adult specimens having been
caught near Kanburi. These two examples, which I
examined alive, differed from the description of the
Indian form in that the disc was marked with numerous,
pale broad lines and angular markings.

Although of not such a fierce disposition as the
common Trionyx cartilagineus, they would when irri-
tated suddenly shoot out their long necks with lightning-
like rapidity and were capable of giving one a vei-y
severe bite.

with 3 narrow white lines, the vertebral (not bifurcated)
starting from the neck and extending to the tip of the
tail, the laterals occupying the upper half of the outer
row of scales and the lower half of the row next and
extending to the vent. Belly with broad transverse bars

in the flank band is common in examples from farther
north (N. Siam), but does not appear to have been
recorded before from the Peninsula. It does not occur
in specimens from Bangkok and the surrounding country
where this snake is common.

Boulenger's statement (p. 217) that this species is
without distinct canthus rostralis is not borne out in
specimens I have examined. In most adults it is well
marked.

One 9 ad. and 1 juv. from Padang, Gunong Tahan.

Previously known from 1 ad. $ and 1 young one.
The adult agrees well with Boulenger's description. The
gular pouch is fully as large as in the male. There are
a few unevenly disposed enlarged scales upon the flanks.
9 upper and 9 lower labials; 72 scales round the middle
of the body, the laterals not much smaller than the
dorsals. The third and fourth fingers are of equal length.

Head and body, 125 mm., tail 300.

The juv. (No. 5990) has a head and body of 46 mm.,
and a tail of 105. Gular pouch well developed. 8 upper
and 8 lower labials. About 80 scales round the body with
enlarged ones as in the adult.

I place these specimens under Boulenger's var. blijthii,
a dubius race as its characters do not coincide with any
definite geographical distribution. In the younger speci-
mens the tibio-tarsal articulation usually reaches to beyond
the tip of the snout, in the adults to not quite so far.

Rec. Ind. Mus., 1920, XX, p. 179.

Seven examples from Kuala Teku and Kuala Tahan
(Nos. 5913-5915 and 6028-6031). The species has hitherto
been found only in Borneo. The largest, a male, is 57 mm.
frofti snout to vent ; the largest female is 55 mm. Two
females taken at the end of November are full of ripe ova.

Colouration. Black above, handsomely spotted and
marked with yellow or yellowish-brown. Five of the speci-
mens have a yellow band starting from the tip of the nose
and passing along the canthus rostralis, the margin of the
eyelid and down the back on either side to the groin. Lower
parts hrown, with small white spots in four examples,
whitish, uniform in two, whitish with black spots in one.

Two of the specimens, both $ , have large irregular
flat glandules on the back.

This species closely resembles R. glandulosa to which
I at first referred them, but it can be recognized by the
more extensive web to the toes, and the more ornate
colouration. The male also has internal vocal vesicles.

Two adult males (Nos. 5911 & 5912) from Kuala
Tembeling, and 1 juvenile (No. 6037) from Kuala Tahan.

Originally discovered in the mountains of Nakon
Sritamarat, Peninsular Siam, this frog was described from
an adult female specimen and a juvenile. A male taken
at the same time, and until recently in my possession,*
agrees well with these individuals from Gunong Tahan.
They have the curious blackish, obliquely-running fine
glandular folds across the back which are to be found only
in one other species of frog from this region, namely
R. lateralis. It turns out also that the frog recorded and
figured by Laidlaw from Kuala Aring, Kelantan (P.Z.S.,
1900) as this latter species, must be referred to miopus.
Miss Procter has kindly examined this specimen, now in
the Museum at Cambridge for me, and confirms my
suspicions as to its identity.

In the three males examined by me the canthus
rostralis is distinct ; the hind limb reaches to between
the nostril and the eye ; the skin of the back is smooth
in one and more or less studded with minute horny
tubercles in two.

The vocal sacs are very prominent, appearing as
distended pouches through a slit on either side of the throat
in front of the fore-arm. They have a large fiat oval gland
at the shoulder and a thick pad on the inner side of the
first finger.

Colour. Greyish-brown above and on the side, the
glandular dorsal fold not darker ; a dark brown patch
enclosing the tympanum ; upper lip lightish ; the limbs
with dark bars ; a series of fine black lines running oblicfuely
downwards from left to right between the dorso-laleral
folds. Below yellowish-white.

The juvenile from Gunong Tahan is coloured pink, like
the juvenile from the type locality.

As the Kuala Aring specimen is the only record of
Rana lateralis in the Malay Peninsula, it must disappear
from the fauna of this region.

Rana cataracta, sp. nov.

Type adult male, Author's No. 6164, collected on Khao
Ram, Nakon Sritamarat Hills, Peninsular Siam, at 300
metres elevation, in Feb. 1922.

Description of type. Vomerine teeth in moderately
strong, oblique series, commencing between the choanae
and extending beyond their posterior borders, equidistant
from each other and from the choanae. Head a little longer
than broad, much depressed ; snout obtusely pointed,
projecting a little beyond the mouth. Canthus rostralis
strong, slightly oblique, deeply concave ; nostril nearer the
end of the snout than the eye ; distance between the nostrils
greater than the interorbital width, which is less than that
of the upper eyelid ; eye large and prominent, its diameter
nearly equal to the length of the snout ; tympanum very
distinct, f the diameter of the eye, not half as long as its
distance from the latter.

Fingers moderately long, the tips dilated into large
discs, those of the third and fourth considerably smaller
than the tympanum ; first finger slightly shorter than
second, third longer than the snout ; subarticular tubercles
large and prominent.

Hind limb long, the tibio-farsal articulation reaching
well beyond the tip of the snout ; heels strongly over-
lapping when the limbs arc folded at right angles to the
body ; tibia once and three-fifths in length of head and body,
longer than the foot ; a feeble tarsal fold ; toes with discs
similar to but smaller than those of the fingers, fully
webbed, the web involving the bases of the discs, slightly
emarginate ; outer metatarsals separated to the base ;
subarticular tubercles moderately large, prominent ; inner
metatSi'sal tubercle oval, somewhat flattened, one-third the
length of the inner toe ; no outer tubercle.

Upper parts finely granulate ; coarsely granulate be-
hind the thighs and upon the sides of the body, the latter
also with numerous small warts ; lower parts smooth. A
moderately broad and fairly prominent glandular dorso-
lateral fold from the eye to the hip.

Colour. Verdant green in life above, greyish in spirits;
sides of the head and body a little darker ; limbs with
indistinct cross bars ; upper lip and the glandule behind
it, white. Lower parts white.

Vocal vescicles internal ; a moderately strong pad on
the first finger. No other sexual characters.

Variation. 21 specimens examined, 1 1 5 3 $ , from
the type locality, 4^ 3$ from Fraser's Hill. Except

276 journal of the F.M.S Museums. I Vol. X,

for some slight differences in measurements, the males do
not differ in any important character from the type
specimen except in having a more prominent, glandular
dorso-lateral fold. Females arc considerably larger.

Two of the males (Nos. 6532, 6534) from Eraser's
Hill are coloured as follows : — Bright green on the back,
sides of body and limbs above brown, the latter with darkish
crossbars ; below white. Two females from the same
locality (Nos. 6535-6) are purplish brown above and on
the sides ; below whitish, the throat, chest and under surface
of limbs heavily powdered with brown.

Eggs large and unpigmented, 2-5 mm. in diameter.

Rana cataracta is closely allied to R. hosii Blgr., and
R. livida (Blyth) .* From the former it differs in the larger
tympanum, more coarsely granulate skin, and very
distinctly in colouration. From the male of R. livida, with
its prominent bladder-like external vocal vescicles, it is
easily distinguished. The females of the two, except for
some slight differences in colouration appear to be
indistinguishable from each other.

From R. chalconata (Schleg.) another near ally which
agrees exactly with it in colouration, and which was found
in company with it on Khao Bam, it differs in the longer
hind limb, more fully webbed toes and in the absence of
the small external metatarsal tubercle.

Remarks. This new frog was first discovered on Khao
Ram, on the banks of a stream famous for its scries of
magnificent waterfalls. It was common at 300 metres
altitude, at a couple of large pools where we were camped
for some days, but was not found on two other hills in the
same range visited on the same trip.

Its habits were those of a true tree frog, perching high
up in bushes, or on the trunks of trees, or hopping about
on the rocks beside the swiftly flowing water. The call of
the male, heard at night only, was a short whistling cry,
sometimes almost a scream, and by it they could be tracked
down with a lantern and caught.

The Rami livida obtained by Wray in the Larut Hills,
Perak, should possibly be referred to this species.

* Also to /?. graminea, Blgr., which appears to differ from
livida chiefly in the presence of a more or less defined glandular
dorso-lateral fold. Originally described from Hainan, this frog
has since been found to be widely spread over Siam and Indo-
China. I strongly suspect the two will have to be united.

The largest 9 is 75 mm., from snout to vent, the
largest $ 44 mm. Another $ , 70 mm. in length, taken
in December, contained about 800 eggs, unpigmented, each
measuring from 1-75 to 2 mm. in diameter. Several
tadpoles with fully developed limbs and diminishing tail,
but with the large ventral sucker still complete were taken
at the same time.

278 Journal of the F.M.S. Museums. [Vol.X,

The amount of black blotching upon the upper parts
of the frog is variable, and may be so extensive as almost to
obscure the green. Some specimens have the throat and
under surfaces of the thighs heavily marked with black also.

The male has vocal vescicles fairly well marked
externally, the skin on either side of the jaw being thinned
and thrown into longitudinal folds.

Rhacophorus leucomystax (Gravenh.).

F.M.P., p. 248.

Three examples from Kuala Tahan and many from
Eraser's Hill. In some of these the tibio-tarsal articula-
tion reaches the tip of the snout, in others well beyoncj.
The hind leg of this common tree-frog varies greatly
in length, and in the large series in my possession from
Siam and Indo-China, the tibio-tarsal articulation reaches
beyond the snout in more than half of them. Philippine
examples evidently do the same (cf. Taylor, Philippine
Amphibia, 1920, p. 289).

Rhacophorus bimaculatus Bouleng.

F.M.P., p. 250.

13 exs. Bukit Fraser.

This tree-frog is very closely allied to R. reinwardti
Boie, and I doubt if it should really be considered specifi-
cally distinct. I have compared the above examples,
and 24 more from Khao Luang in the Nakon Sritamarat
Hills, Peninsular Siam (unfortunately, only one more than
half grown) with 4 specimens of typical reinwardti from
Java. None of the differences claimed by Boulenger for
them will stand.

The vomerine teeth may be in slightly oblique series
or perfectly straight. The cutaneous folds above the vent
along the sides of the arms and legs may be slightly or
strongly developed. No black spots are present on the
membrane between the fingers and toes of the Siamese
examples, but are present in half the series from the
Malay Peninsula.

The character in which the two forms however do
consistently differ is in the size of the discs of, and extent
of the web between, the fingers and toes. In reinwardti
the finger discs are always larger than the tympanum and
the membrane is fuller, usually extending to the disc of
the third finger. In bimaculatus the discs are not larger,
and often smaller, than the tympanum, and the web never
reaches the disc of the third finger.

In addition the membrane of both fingers and toes
in reinwardti are wider, allowing a more complete
separation of the digits. Thus when the fingers of this
frog are fully extended, the first and fourth form a straight

1922] Smith: Reptiles and Batrachians. 279

line; in bimaculatus they make an obtuse angle. The
external metatarsals are completely separated in rein-
wardti, in bimaculatus not completely.

Tadpoles taken on Fraser's Hill and bred out by me
agree entirely with van Kampen's description of the tad-
pole of reinwardti (Nat. Tijd. Ned. Ind., LXIX., 1909,
p. 43).

The colouration of R. bimaculatus in life shews
considerable variation, the upper parts ranging through
various shades of green, grey, pink or brown, usually
uniform but sometimes with an indistinct dark) (upon
the back. Below dull yellow the membrane between the
fingers yellow, between the toes red or orange, this
colour sometimes including the upper arm, flanks and
a band along the thighs. Very young specimens are
light brownish-green above, with a white throat and belly
and yellow limbs.

R. reinwardti appears to have accomodated itself to
more lowland conditions, thriving at Buitenzorg, altitude
250 m., while R. bimaculatus as far as the Malay Peninsula
and Siam is concerned has not been found below 700 m.

Philautus brevipes (Bouleng.).

Ixaliis brevipes, Bouleng, Journ. F.M.S. Mus. III., 1908, p. 63,
pi. IV., fig. 1; F.M.P., p. 253.

A fine series of 16 specimens of this little tree-frog,
hitherto known only from a single example. (Nos. 5970
and 6007 to 6021), One was taken by Mr. Chasen at Kuala
Teku on a broad leaf overhanging the water, the remainder
are from Camp Padang. The type was obtained by Mr.
Robinson on Gunong Tahan at 1,000 metres.

The series agrees well with the description. The tibio-
tarsal articulation may reach to the anterior border of the
eye. The tympanum varies in distinctness, and is always
smaller than the disc of the third finger. The skin of the
back is smooth in some, finely shagreened in others.

As is common with many species of Philautus the
colour is variable. About half the scries shew the dark
patch on the back, more or less as figured in the description
of the type. In others the back is uniformly but coarsely
speckled with black all over. Some have no dark bars to
the Ihnbs. Greyish olive is the predominating colour above,
except in one example which is reddish brown.

The example from Kuala Teku (No. 5970) is pale grey
above (under the glass dark grey finely vermiculated with
buff), and with a broad irregular buff band along either
side of the back. This specimen, the largest, measures 36
mm^ from snout to vent.

Several of the females contain ripe ova, the eggs being
large, few and pigmented. Diameter 2 mm;

p. 39, pi. IV., fig. 1; F.M.P., p. 254.

One example, Kuala Teku (No. 5929) ; one example
Wray's Camp (No. 5930).

Boulenger's description, drawn up from a single
example, agrees entirely with these two specimens except
in colouration, a point of little significance with many of
the members of this genus, so greatly may they vary both
in colouration and in markings.

No. 5930 has the snout obliquely pointed as in the
figure, the other, a larger one, has it more acutely pointed
owing to the presence of a distinct dermal tip.

Both specimens are dark brown colour above, the
smaller one uniform, the larger with indistinct paler
mottlings and indications of a dark X ; below pale yellowish-
brown, heavily spotted with dark brown.

Boulenger has compared this species with his
P. vermiculatus ; 1 can find nothing, however, except
colouration and a slightly narrower interorbital region, to
separate it from the Javan P. aurifasciatus Schlegel, with
a specimen of which I have compared it.

Kalophrynus robinsoni, sp. nov.

Type, author's number 5935, collected at Wray's Camp
in Oct. 1920 ; presented to the British Museum.

Description of the type. Tongue elliptic, entire.
Snout short, truncate, projecting slightly beyond the
mouth ; canthus rostralis distinct, loreal region vertical,
feebly concave ; interorbital region broader than the upper
eyelid ; tympanum distinct, two-thirds the diameter of the
eye. First and second fingers very short, not half the length
of the third, fourth shorter still ; toes one-third webbed,
the web extending as a fringe along the outer sides of the
toes ; fifth toe shorter than the third ; tips of fingers and
toes bluntly pointed ; a feebly developed oval inner
metatarsal tubercle and a rounded outer one. The tibio-
tarsal articulation reaches the tympanum.

Skin of the back granular, with small scattered
tubercles ; a series of tubercles along the dorso-lateral
region from the eye to the groin ; belly and groin with
large, coarse granules ; throat with finer granules ; a
curved fold from the eye to the shoulder.

Light brown above with dark brown markings, in
particular a large one on the back extending forwards in
two branches to the eyelids, and backwards, in two longer
branches to the groins ; sides of head and body very dark
brown, this colour sharply defined from the light brown

1922] Smith: Reptiles and Batrachians. 281

of the back ; limbs with dark cross bars, and a dark patch
enclosing the vent and extending along the back of the
thighs. Below yellowish, spotted and speckled with brown.

From snout to vent 17 mm.

Variation. Five examples from the type locality
(author's numbers 5934 to 5938 inclusive) and one more
from Kuala Teku (5942) do not show much variation from
the type specimen. The tympanum is not so distinct in
two examples ; in one the series of tubercles along the
doso-lateral region is very conspicuous, and there is in
addition another series along the hinder side of each thigh
as in K. pleuro stigma. Two specimens have a pink tinge
upon the upper parts ; the dark forked mark on the back
varies considerably both in extent and shape.

Kalophrynus robinsoni is related to K. heterochirus
Boulenger, from Borneo, from which it differs in the
shorter hind limb, shorter third finger, the strongly
tubercular skin and distinctive colouration.^

The specimens here described are evidently very
young. Their characters however are quite distinct
The dermal ridge across the palate behind the choanae
it obtusely V shaped and interrupted in the mid-line, as in
K. pleiirostigma ; the ridge in front of the oesophagus is
pronounced and strongly denticulate, while the one anterior
to it is curved and less strongly denticulate. Boulenger's
figure of K. pleurostigma in F.M.P., 257, represents the
anterior ridge as a continuous curve. In 22 specimens in
my collection from various parts of Siam and Indo-China,
it is in each one interrupted in the mid-line for some
distance. Miss Procter informs me that the palatal ridge
of K. heterochirus is almost straight, and is just inter-
rupted in the middle.

Microhyla butleri Bouleng.
F.M.P., p. 261.

One juvenile from Kuala Teku ; four adults from
Eraser's Hill.

Recently also I have examined a specimen frorn the
He-Ho plain, Southern Shan States, Burma, sent me by Dr.
Anandale ; a considerable extension of the known
geographical range of this frog.

Microhyla berdmorei (Blyth).
F.M.P., p., 263.

Two juveniles, one from Kuala Teku, the other of
unknown origin — the label being lost. It is certainly
however from somewhere on this mountain.

This specimen a $ (No. 6050) is somewhat remarkable,
in that although only 17 mm. in length from snout to vent

1. Kindly compared for me by Miss Procter with the type
specimen, now in the British Museum.

agrees with M. berdmorei.

One adult $ (No. 5928) with ripe ova collected at Kuala
Tahan, in January. This is the first record of this burrow-
ing frog from the mainland of Asia, although it is well
known in the Archipelago.

Phrynella pulchra Bouleng.
F.M.P., p. 265.

A male and female taken in copula in September at
Kuala Tahan (Nos. 5931, 5932). They were caught in the
bottom of a boat in a pool of water that had collected there
from a storm of the previous night. Eggs large and
pigmented, the vitelline sphere measures 1*5 mm. in
diameter. The male has the pad at the base of the first
finger slightly larger than that of the female, but there
are no other characters separating the sexes.

XXI. A BUTTERFLY NEW TO THE MALAY
PENINSULA.

By H. M. Pendlebury, F.E.S.
Systematic Entomologist, F.M.S. Museums.

Amongst some insects recently obtained in the Main
Range north of Gunong Berumbun is a butterfly of a
species not yet recorded from further south than
Tenasserim : —

FAMILY NYMPHALIDAE.

Sub-family Satyr inae.

Lethe verma Koll.

Lethe verma Fruhst. in Seitz' Macrolepidoptera, IX, p. 324;
Bingham, Fauna of British India, Butterflies I., p. 84.

$ , Lubok Tamang, Pahang, F.M.S., 4,000 feet, Sept.
8th 1922. Native Collector.

This individual which has an expanse of 68 mm., the
prominent ochreus-white oblique discal band on the fore-
wings beings 7 mm. broad in the middle, comes nearest
to the wet-season form L. V. sintica which, according to
Fruhstorfer " . . . . presents very definitely the aspect
associated with a rainy district ; compared with verma
from the dry West of the region." L. v. stenopa Fruhst.,
recorded from Tenasserim, ".... shows a reversion to-
wards verma ; comes likewise from districts with a small
rainfall and hence again with predominantly dry-season
facies."

Previously recorded from N.-W. and E. Himalayas ;
Assam ; Khasia Hills ; Burma and Tenasserim.

Fruhstorfer, I.e., places this species under group
Hermias, Fruhst. and records six subspecies as follows: —

L. V. verma Koll. Common in Kashmir and
Mussurie.

L. V. sintica Fruhst. Sikkim and Assam.

L. V. stenopa Fruhst. Tonking, Hainan, Shan States
and Tenasserim.

L. V. laticincta Fruhst. Wet season form, China.

L. V. cinctomani Fruhst. Melanotic island extreme,
Formosa.

L. V. satarnus Fruhst. Mountain form, Omeishan,
W. China.
